Question

Fred has a large piece of sugar that is not dissolving in his drink. How could he get the sugar chunk to dissolve faster?

by placing it in the refrigerator
by breaking it up into smaller pieces
by letting it dissolve naturally without agitation
by adding a larger piece so the smaller one will dissolve

Answer 1

B

by breaking it up into smaller pieces

Answer 2

Answer: by breaking it up into smaller pieces

Explanation:

Rate of solubility of solids in liquids depend on 4 main factors:

1.) Temperature: Increasing the temperature means more solute can be dissolved in the given amount of solvent because the energy of the solute particles increases and more it can interact with the solvent particles. The rate of dissolution of solid also increases in liquids.

2.) Size of the solute particles: If the solute particles is present in smaller size, more it can be dissolved because decreasing the size increases the surface area of the solute particles. Hence, the dissolution increases.

3.) Stirring: This process brings fresh solvent particles to come in contact with the solute particles and hence, fast stirring increases the rate of dissolution.

Thus the sugar chunk can be dissolved faster by breaking it into smaller pieces.
