Question

Generally, what happens to the rate of dissolution for a solid solute when you change from stirring a solution to not stirring it?

Answer 1

Explanation:

When we stir the solute in a solution then rate of dissolution increases as size of solute particles rapidly decreases on stirring.

On the other hand, when we do not stir the solute in a solution then rate of dissolution decreases.

For example, when we stir salt in water it readily dissolves but when we do not stir salt in water then either it takes long time to dissociate or it does not get dissolved.

Answer 2

The rate of dissolution of a solid solute into the solution decreases when you stop stirring it. Generally, stirring increases the dissolution rate of a solid into a solution. An example is coffee with sugar, the sugar dissolves faster when stirred versus when left to dissolve on its own.
