Question

explain why Be(oh)2 is almost in soluble in water while ba (oh)2 is soluble?​

Answer 1

Answer:

Be(OH)2 and Mg(OH)2 are almost insoluble, Ca(OH)2 is sparingly soluble while Sr(OH)2 and Ba(OH)2 are fairly soluble. This is due to increase in size of the cation and decrease in their lattice energies on moving down the group.
