Question

Equimolar solutions of the following substances were prepared separately.Which one of these will record the highest pH value?
1.Barium chloride.
2.Aluminium chloride.
3. Lithium chloride.
4.Beryllium chloride.

Answer 1

barium chloride will have the highest pH value

Answer 2

Answer: 1st option is the correct answer

Explanation: in rest of the options cationic hydrolysis will take place so pH will be less than 7

but in case of BaCl2 there will be no cationic and anionic hydrolysis so pH will be equal to 7
