Hello, I need help solving the 3 parts of this question.
Part - Factors affecting the dissolution process The rate at which a solute dissolves in a solvent depends on the kinetic energy of the soluton, theme of contact and the surface area of contact between the solute and the solvent particles. Both endothermic and exothermic dissolution processes will respond similarly to each factor, however the charge may be more pronounced depending on the thermodynamic penters of the reaction. As...

Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...

QUESTION 4
If you take a 171 mL of a 1.4 M NaCl solution and dilute it to
500 mL, what is the molarity of the final solution?

QUESTION 10
Information - Colligative
Properties
Colligative properties of solutions are those properties which
depend only on the number of dissolved solute particles in solution
not the chemical properties of the solute. For example when a
solute is dissolved in a solvent, vapor pressure

1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...
