Effect of impurities on critical solution temperature?
Impurities can lower the critical solution temperature by disrupting the interactions between solvent and solute molecules. This interference weakens the solute-solvent interactions, making it easier for the solute to dissolve at lower temperatures. The impurities effectively destabilize the solute-solvent system, resulting in a decreased critical solution temperature.
What 2 solute molecules mixed with the solvent molecules in a solution cause the freezing point of a solution to be than it is for an equal volume of pure?
lower, solvent, lower, solvent
What does solubility depend on?
Solubility depends on the interaction between the solute and solvent molecules. Factors that influence solubility include temperature, pressure, polarity of the solute and solvent, and the presence of any common ions. Ultimately, solubility is determined by whether the forces holding the solute molecules together are weaker or stronger than the forces between the solute and solvent molecules.
Why do solids partly dissolve?
Your question is not clear; some solids have a great solubility, another are practically insoluble. The solubility depends on the nature of solvent, the nature of the solute, polarity of the molecules, pressure, temperature, the presence of other substances in the solution.
Is salt solution a conductor or insulator of electricity?
A salt solution in water is a conductor, due to the disassociation of the salt molecules into oppositely charged ions in the presence of the polar water molecules. A salt solution in a nonpolar solvent would likely be an insulator, as the salt molecules probably would not dissociate.
When solute particles are added to a pure solvent in a closed container at a constant temperature and pressuer the vapor pressure?
decreases because the presence of solute particles impedes the escape of solvent molecules into the vapor phase, leading to fewer solvent molecules reaching the vapor phase.
What effect does adding a solute to a solvent have on the freezing point of the solvent?
the temperature at which the solution freezes is lowered.
What is the name of the pressure that must be exerted on a solution to prevent the passage of solvent molecules into a solution when the solution and solvent are separated by a semipermeable membrane?
Osmosis.
What is the term for a cluster of solvent molecules surrounding a solute particle in solution?
Solvent Cage
What is the solution process with water as the solvent?
The solution process with water as the solvent involves the solute particles being surrounded by water molecules and dispersed throughout the solvent. This is due to the polar nature of water molecules, which allows them to interact with the solute particles and break them down into individual ions or molecules. The result is a homogeneous mixture where the solute is evenly distributed in the solvent.
Why is vapor pressure of solution of glucose in water lower than that of water?
The presence of solute particles (glucose) in a solvent (water) disrupts the formation of vapor molecules at the surface, lowering the vapor pressure. This is due to the solute molecules occupying some of the space where solvent molecules would have evaporated from.
What are property of a solution?
The presence of solutes in a solution alter the ability of solvent molecules to interact. This affects the ability of the solvent to go through phase changes. These are called colligative properties. The basic colligative properties are boiling point, freezing point, osmotic pressure, and vapor pressure.
