Question

when a mixture is stirred
a the rate of dissolving stops.
b the rate of dissolving will increase.
c the rate of dissolving will decrease.
d the rate of dissolving will remain constant.

Explanation:

Stirring a mixture brings fresh solvent into contact with the solute, and moves the already dissolved solute away from the solute surface. This reduces the concentration gradient barrier, making the dissolving process faster.

Answer:

B. the rate of dissolving will increase.
