Question 11 • Chemistry

Which of these factors will cause a solid solute to dissolve faster?

Answer
A
increasing the surface area of solute
B
increasing the amount of solute
C
increasing the amount of solvent
D
increasing the air temperature

Explanation

Increasing the solute’s surface area exposes more of it to the solvent at once, so more particles can dissolve at the same time. For example, crushed solid dissolves faster than a single large chunk. Increasing the amount of solvent may allow more solute to dissolve overall, but it does not directly make a solid dissolve faster.
