What happens to the stability of carbonates and hydrogen carbonates...

What happens to the stability of carbonates and hydrogen carbonates as you move down the alkali metal group in the periodic table?

Options

  1. AThe stability of both carbonates and hydrogen carbonates increases.
  2. BThe stability of both carbonates and hydrogen carbonates decreases.
  3. CThe stability of carbonates increases, but the stability of hydrogen carbonates decreases.
  4. DThe stability of carbonates decreases, but the stability of hydrogen carbonates increases.

Correct answer

A. The stability of both carbonates and hydrogen carbonates increases.

Step-by-step solution

As you move down the alkali metal group in the periodic table, the electropositive character of the metals increases, leading to increased stability of both carbonates (M2CO₃) and hydrogen carbonates (MHCO3).
