Question

1. which would increase the solubility of the drink powder mix?

a. warmer temperature water
b. having more powder
c. cooler temperature water
d. putting ice in the drink

Explanation:

• For most solids (like drink powder), solubility increases with temperature.
• Warmer water provides more energy for solvent - solute interactions, breaking the intermolecular forces in the solid and allowing more powder to dissolve.
• Having more powder (\(B\)) doesn't change solubility (a property of the solute - solvent system at a given temperature), it just may lead to more undissolved powder if solubility limit is reached.
• Cooler water (\(C\)) and putting ice (\(D\)) (which lowers temperature) decrease solubility for most solids.

Answer:

A. warmer temperature water
