What happends when chromates are kept in acidic solution and dichromates in the alkaline solution?

Explanation

To solve the question regarding the behavior of chromates and dichromates in different pH environments, we can break it down into several steps:

### Step 1: Understanding Chromates and Dichromates
Chromates (CrO₄²⁻) and dichromates (Cr₂O₇²⁻) are two different forms of chromium oxoanions. They are interconvertible depending on the pH of the solution.

### Step 2: Chromates in Acidic Solution
When chromates are placed in an acidic solution, they undergo a chemical reaction where they convert into dichromates. The reaction can be represented as follows:
