Question

Pls solve

103 Minimum pH is shown by aqueous solution of
(1) 0 1 M BaC12
(2) 0 1 M Ba(NO3)2
(3) 0 1 M BeC12
(4) 0 1 M Ba(OH)2

Raveena Sharma · Accepted Answer

The correct option is (3)

This is because:

-Acidic character increases across a period from left to right
- Acidic character decreases down the group

Using above two statements, we see that Barium salts are basic in
nature, while Be salt is acidic as Be is metalloid

Thus, BeClâ€‹2 has the lowest pH

Pls solve 103. Minimum pH is shown by aqueous solution of (1) 0.1 M BaC12 (2) 0.1 M Ba(NO3)2 (3) 0.1 M BeC12 (4) 0.1 M Ba(OH)2
