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...

When some ionic solids (for example, potassium chloride) are dissolved in room temperature water, the beaker becomes cold. a) Based on this observation, is the enthalpy of dissolution positive, negative or zero? b) Since potassium chloride spontaneously dissolves in water at room temperature, does the entropy of the system increase or decrease as the solid dissolves? Briefly explain your answer. c) Based on your answers to parts a) and b), will potassium chloride become more soluble or less soluble as...

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...
