Question

name a metal carbonate which is soluble in water

Answer 1

Generally the metal carbonates are insoluble in water because the strength of ionic bond is so high that it is not possible for the solution to break the force.

Moreover the carbonate ion carries a positive charge of 2, therefore it can be said that only sodium and potassium carbonates are soluble in water.

K2CO3
