Question

If the valency of two elements A and B are 3 and 2 respectively, then the formula of sulphate of B and the chloride of A respectively are
(1) BCI, ASO
(2) A CI3, B3(SO2)2
(3) BSO4, ACI
(4) ACI, B(SO2)​

Answer 1

Answer:

answer =  ACl3 , BSO4

Explanation:

Given - a) valency of A = 3

            b) valency of B = 2

TO FIND - formula of sulphate of B and chloride of A

NOW - 1) Sulphate = S04^-2

           2) Chloride = cl^-1

reacting respective species we get ⇒ B^2 + SO4^- 2 = BSO4

b) A^+3  + Cl^-1 = ACl3.
