Why only a certain amount of solute will dissolve in water?
When solute dissolves in solvent it is being surrounded by the solvent's molecules. Because there are a finite number of molecules in a given amount of solvent, there is a limit to how much solute can fit in.
Does sugar dissolve faster than salt when all other variables are the same?
Sugar dissolves in a liquid faster than salt does. The reason is that sugar is less dense as a solute than salt is, leading to it dissolving in the solvent faster as it would fit into the 'empty gaps' that the solvent has at a much faster rate, which is how substances dissolve.
Why water is sometimes referred to as the universal solvent because it is a large molecule and can fit easily among the molecules of many solutes?
Because water is a soulte and solvent is not
What is the particle theory of dissolving?
When a solid dissolves, the solid (solute) and the liquid (solvent) will form solution. When a solid dissolves on mixing, its particles will break apart hence forming loose associations with the liquid particles. This random mixing of particles from both solid and liquid that is called dissolving process. A solid will not dissolve in a liquid if its particles are unable to form these association with the respective liquid particles. This is a reversible process. Solute can be obtained back by evaporation etc.
Use the particle theory to explain how distillation works?
The particle theory states that there are spaces between all particles. This means that, in a glass of water, there are many water particles but also many empty spaces. The same is true in a cup of sugar. When you look at sugar, you can see many crystals of sugar. Each sugar crystal contains enormous numbers of invisible sugar particles. When sugar dissolves, the sugar particles separate and mix with the water particles. You can draw a diagram showing a model of sugar particles dissolving in water particles. As the sugar particles separate, the smaller water particles fit into the spaces between the larger sugar particles. The water and sugar particles are attracted to each other so they move closer together when they are mixed. This is why the total volume is often slightly less than the volumes of the two separate components. by TEDDYCowleyaTrust: 1108Elements And Compounds SupervisorRecommend Supervisor »RushabhyTrust: 247Elements And Compounds SupervisorRecommend Supervisor »ChristinoTrust: 396Elements And Compounds SupervisorRecommend Supervisor »Cwh130395Trust: 221Elements And Compounds SupervisorRecommend Supervisor »JEKTrust: 4498Science Of Matter And Energy SupervisorRecommend Supervisor »BlueTrust: 6054Science Of Matter And Energy SupervisorGoogle Profile » Recommend Supervisor »GandertonTrust: 4660Science SupervisorGoogle Profile » Recommend Supervisor »HooweestikTrust: 3337Science SupervisorRecommend Supervisor »»
What does a solute need to dissolve in a solvent?
A general principal to follow is like dissolves like. For instance, water, a polar molecule with a small charge distribution, is very good at dissolving ionic compounds, which are made of charged ions.
Why add Solute to solvent instead of solvent to solvent?
Well, honey, you add solute to solvent because that's just how chemistry works. The solute dissolves in the solvent, not the other way around. It's like trying to fit a square peg into a round hole - it just ain't gonna work. So save yourself some time and do it the right way, okay?
Why does a solute depress the freezing point of a solution?
A solute depresses the freezing point of a solution because the solute can not fit perfectly into the crystal lattice of the solid solvent. The normal crystal lattice is the lowest energy arrangement of the molecules or ions of the solid solvent. Therefore, the disordered lattice of a solvent freezing in the presence of a solute has at least slightly higher energy than the lattice of a solid pure solvent and requires at least a slightly lower temperature to solidify.
What is dilute solution and concentration?
A dilute solution is a solution in which there is a small amount of solute (the thing that gets dissolved) compared to the total amount of possible solute that can be dissolved in the solvent (the thing that does the dissolving). A concentrated solution is when there is a lot or all solute that can possibly fit in the solvent.
Why do the particles of a solution not separate?
Particles in a solution do not separate because they are evenly distributed and surrounded by the solvent molecules. The particles are constantly moving and colliding with solvent molecules, preventing them from clumping together and settling out. This uniform distribution results in a stable mixture that maintains its homogeneity over time.
A solute makes the freezing point of a solution lower than the freezing point of the pure solvent because?
The phenomenon you're describing is generally referred to as freezing-point depression, the lowering of the freeze point of a liquid (or solvent) by adding another compound. Freezing point depression is a phenomenon driven by entropic changes in the system containing solvent and solute. As the system is frozen, the solvent forms crystals of high purity regardless of solute molecules being present while solvent crystallizes. Replacement of any solute in the crystal with a solvent molecule takes place spontaneously, since the inability of solute molecules to fit well into the ordered crystal makes the solute-solvent substitution thermodynamically favorable. As the freezing proceeds, solvent molecules continue to leave the liquid state and incorporate into the solid crystal, with each such occurrence leaving behind a smaller volume of liquid in which solute molecules can occupy. The shrinking of liquid volume occupied by a fixed number of solute molecules reduces the dispersion of solute molecules in the liquid, resulting in a reduction of entropy of the solute molecules. Thus, additional energy is required to match the reduced entropy of the solute molecules with that of the solid solvent crystal. The energy required (versus pure solvent) to gap the entropic difference (thus difference in chemical potential) to establish equilibrium but at a freezing temperature lower than that of the pure substance. Note that at low solute concentrations, freezing point depression is a property that depends solely of the number of solute particles and physical properties of the solute. Such properties are called colligative properties.
Is smoke a solute and solvent?
Oh honey, bless your heart for trying. Smoke is actually a mixture of particles and gases, so it doesn't fit neatly into the solute or solvent categories. It's like trying to fit a square peg into a round hole - it just doesn't work. But hey, at least you're thinking about chemistry, so good for you!
Why only a certain amount of solute will dissolve in water?
When solute dissolves in solvent it is being surrounded by the solvent's molecules. Because there are a finite number of molecules in a given amount of solvent, there is a limit to how much solute can fit in.
What is an example of a solution in which the solute and solvent are not easily distinguishable?
An example of a solution where the solute and solvent are not easily distinguishable is a metal alloy, such as bronze. In bronze, copper is the solvent and tin is the solute, but they are completely mixed at the atomic level, resulting in a uniform composition throughout the mixture.
How do particles in rocks fit together?
Particles in rocks fit together through a process called lithification, where sediments are compacted and cemented together. The size, shape, and arrangement of the particles determine the texture and structure of the rock. Different types of rocks, such as sedimentary, igneous, and metamorphic, have distinct characteristics based on how their particles are arranged.
Does sugar dissolve faster than salt when all other variables are the same?
Sugar dissolves in a liquid faster than salt does. The reason is that sugar is less dense as a solute than salt is, leading to it dissolving in the solvent faster as it would fit into the 'empty gaps' that the solvent has at a much faster rate, which is how substances dissolve.
What are the factor that affect solubility?
Factors that affect solubility include temperature (usually higher temperature increases solubility), pressure (for gases), the nature of the solute and solvent (like dissolves like), and the presence of other solutes that may compete for interactions with the solvent molecules.
