Question

what is common ion effect ? explain.​

Answer 1

Answer:

The common-ion effect refers to the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate. This behaviour is a consequence of Le Chatelier's principle for the equilibrium reaction of the ionic association/dissociation.

Answer 2

Answer:

Hi

Explanation:

It is a phenomenon of slowing or reversing of the reaction when a salt is added while the reaction is going on.

That salt contains the common ion which is being produced as a product.

As the rate of reaction is inversely propertional to the concentration of the product.

The reaction will slows down to very low rate or even can move in reversed direction.

This phenomenon is called common-ion effect.

2CH3COOH+2NaOH -----> 2CH3COONa +2H2O

if we add CH3COONa in the container the reaction will slow down.
