What else can I help you with?
Do the volume of the material stays constant when a solution is diluted?
No, the volume of the material increases when a solution is diluted because you are adding more solvent to decrease the concentration of the solute. Diluting a solution does not change the total amount of material present, but it does change the volume in which that material is dispersed.
How do cells respond to environments with different solute concentrations?
There are three types of solute concentrations, Isotonic, Hypotonic and Hypertonic. The prefix refers to how much solute is in the solution as compared to the inside of the cell. In Isotonic, the cell and solution have the same concentration of solute, so the cell stays the same size. In Hypertonic, the cell has less solute than the solution, and therefore gives water to to balance out and shrivels. In Hypotonic, the cell has more solute than the solution, and accepts water from the solution, thereby swelling, which is potentially beneficial in plant cells but can destroy animal cells. I hope this answers your questions. Isotonic is the best for animals, hypotonic is the best for plants.
How do the solvent particles break up from the solute?
When a solute dissolves it breaks apart into its individual particles. The solute and solvent particles mix together and become totally mixed up. That's why a solution is a mixture! As the solute and solvent particles become mixed up, no matter is lost. The overall mass stays the same.
When sugar is dissolved in water What about its weight?
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
What is the solid called that is left behind after filtration?
Residue.or precipitate
What is different about mixture and solution?
In a mixture, the solute is not completely dissolved by the solvent and so stays detectable (a heterogeneous mixture). In a solution, the solute is completely dissolved and cannot be distinguished from the solvent (a homogeneous solution)

When solid is dissolved in a liquid?
When a solid is dissolved in a liquid, the liquid is said to be the solvent and the solid is to be the solute. The liquid that you get after dissolving the solid into the liquid is called the solution. When a solute dissolves, the solvent particles attract the particles of the solute away which breaks the cluster of particles apart. After dissolving enough amount that the solvent cannot dissolve more, the solution is said to be saturated. It is the state when the solution cannot dissolve anymore solute. The opposite of solution is suspension. A suspension is when the solute cannot be dissolved (that is, it is insoluble) into the solvent and stays suspended in the solvent. A suspension is translucent and the suspended particles can be easily seen. While, in a solution, the particles are soluble and complete dissolve into the solvent. A solution is transparent and the particles are too small to be seen through naked eyes.

When the acidic solution is added to the basic solution what happens to the pH does it increase decrease or stays the same?
When an acidic solution is added to a basic solution, the pH will decrease. This is because the addition of the acidic solution will neutralize some of the hydroxide ions in the basic solution, resulting in a decrease in pH.
How do the solvent particles break up from the solute?
When a solute dissolves it breaks apart into its individual particles. The solute and solvent particles mix together and become totally mixed up. That's why a solution is a mixture! As the solute and solvent particles become mixed up, no matter is lost. The overall mass stays the same.

How do crystals form?
Crystals start to form by a process called nucleation. This process can either start with the molecules themselves (unassisted nucleation), or with the help of some solid matter that is already in the solution (assisted nucleation). When molecules of the "solute" (the stuff of which you want to grow crystals) are in solution, most of the time they see only solvent molecules around them. However, occasionally they see other solute molecules. If the compound is a solid when it is pure, there will be some attractive force between these solute molecules. Most of the time when these solute molecules meet they will stay together for a little while, but then other forces eventually pull them apart. Sometimes though, the two molecules stay together long enough to meet up with a third, and then a fourth (and fifth, etc.) solute molecule. Most of the time when there are just a few molecules joined together, they break apart. However, once there becomes a certain number of solute molecules, a so-called "critical size" where the combined attractive forces between the solute molecules become stronger than the other forces in the solution which tend to disrupt the formation of these "aggregates". This when this "protocrystal" (a sort of pre-crystal) becomes a nucleation site. As this protocrystal floats around in solution, it encounters other solute molecules. These solute molecules feel the attractive force of the protocrystal and join in. That's how the crystal begins to grow. It continues growing until eventually, it can no longer remain "dissolved" in the solution and it falls out (as chemists like to say) of solution. Now other solute molecules begin growing on the surface of the crystal and it keeps on getting bigger until there is an equilibrium reached between the solute molecules in the crystal and those still dissolved in the solvent. Pretty much the same thing happens as in unassisted nucleation, except that a solid surface (like a stone, or brick) acts as a place for solute molecules to meet. A solute molecule encounters the surface of a stone, it adsorbs to this surface, and stays on it for a certain time before other randomizing forces of the solution knock it off. Solute molecules will tend to adsorb and aggregate on the surface. This is where the protocrystal forms, and the same process as described above happens. You can probably see why, from what I wrote above, crystals grow fastest in a solution in which the concentration is near saturation. If there are more solute molecules in a given volume, then there is more of a chance they will meet one another. You also don't want to heat up the solution because that acts as the major randomizing force in solution which causes the aggregates of molecules to break up.

What happens to a red blood cell when exposed to isotonic solutions?
When a red blood cell is exposed to an isotonic solution, there is no net movement of water into or out of the cell. This means that the cell maintains its normal shape and volume, as the concentration of solutes inside and outside the cell is balanced.
What is the name for when a solid mixes with a liquid and stays mixed?
When a solid mixes with a liquid and stays mixed, it forms a homogeneous mixture called a solution. In a solution, the solid particles are evenly distributed throughout the liquid, giving it a uniform appearance.
When sugar is dissolved in water What about its weight?
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
