1.	The hydroxides and carbonates of Na and K are solube in the water while those of Mg and Ca are spairingly soluble .Explain.
Answer» SOLUTION :Lattice energies of the hydroxides and CARBONATES of Na and K are much smaller than those compounds of and MG.(This is due to the LARGER size of Na and K compared to Mg and Ca.)
