The valency of 'X' is 3 and the formula for its hydroxide is .
Given:
The formula of sulphate of an element X is .
To Find:
1. The valency of 'X'.
2. The formula of its hydroxide.
Solution:
The formula of sulphate of an element X is .
Let us assume the valency of X is y and we know the valency of sulfate ion is 2.
2y-6=0
⇒y= 3
The valency of X is 3.
Now the valency of hydroxide is 1.
So the formula is .
Hence, the valency of 'X' is 3 and the formula for its hydroxide is .
