Question

Chromate ions react according to the following equation, where the left side of the reaction is yellow and the right side is orange.
CrO42– + 2H+ ⇄ Cr2O72– + H2O

A student adds sodium hydroxide (NaOH) to the solution at equilibrium. In one to two sentences, describe and explain any changes to the solution that the student will observe.
please helpp

Answer 1

NaOH is a base and addition of NaOH will cause the left reaction to proceed and the solution turns yellow.

What is chemical equilibrium?

Chemical equilibrium refers to a dynamic stare in which the forward and reverse reactions are occurring at the same time at the same rate.

Any change in the reaction conditions will cause equilibrium to shift either to the left or right.

In the given equation, addition of acid will result in the forward reaction proceeding and the solution turns orange.

The left reaction is favoured on addition of base.

Since NaOH is a base, addition of NaOH will cause the left reaction to proceed.

The solution turns yellow

Answer 2

The change to the solution is that the addition of NaOH will cause the left reaction to proceed and the solution turns yellow.

What is a solution?

A solution means a special type of homogeneous mixture that is composed of two or more substances.

It should be noted that a change in the reaction conditions will cause the equilibrium to shift either to the left or right.

In this case, the addition of NaOH will cause the left reaction to proceed and the solution turns yellow.
