Question

Electrovalency of Ca in Ca4 (PO4)2, is


​

Answer 1

Answer:

For Ca the electrovalency is 3/2

Explanation:

Ca=x

4x-3(2)=0

thus x=2/3

Answer 2

Answer: The correct formula is Ca3(PO4)2

Electrovalency of Ca is +2

Explanation: Let, valency of Ca is x.

x*3 + (-3)*2 = 0

or, 3x = 6

or, x = 2

Therefore, electrovalency of Ca is +2
