Question

M is a brivalent metal.Write down the steps to find the chemical formulae of its compounds formed with the radicals ,sulphate and phosphate

Answer 1

M has valence 2.
Thus its sulphate=MSO4 since both have valency 2 and the valency gets canceled.
Its phosphate=M3(SO4) 2 since phosphate ion has valency 3 and it gets exchanged!
Hope it helps!!!
