Question

The solubility of alkali metal carbonates.............as one goes down the group.

Answer 1

increases down the group

Answer 2

The following elements are included in the periodic table in Group 1: “Lithium”, “Sodium”, “Potassium”, “Rubidium”, and “Caesium”.  

The general electronic configuration of elements of Group 1 is ${ ns }^{ 1 }$

They tend to donate their valence electron to strong ionic bonds in the last shell. In their respective periods, they have the least nuclear charge.

Solubility of the carbonates increases as we go down the Group 1 elements. The least soluble hydroxide in Group 1 is lithium hydroxide.

The solubility of alkali metal carbonates increases as one goes down the group.
