Q20) The equivalent weight of an element is 4. Its chloride has V.D. 59.25. Then the valency of element is ... [ BHU 1987]

SOLUTION

Molecular weight=2 ×V.D=119

Let x be the valency of metal then formula becomes MClx

Then molecular weight of metal=equivalent weight × valency

Now 119=x(4) + x(35.5)

∴ x=3

Answer: (b)
