SODIUM acetate when dissolved in water ionises COMPLETELY and the ions formed react with water forming weak acid and strong base.

CH3COONa +H2O gives CH3COOH +

Acetic acid being weak acid ionise partially but sodium hydroxide is strong electrolyte and ionises completely. So there remains some excess

OH–

in solution. HENCE the solution of sodium acetate is basic in nature.

The FORMULA of 'X' is MgAl₂O₄ [Option.b]

Explanation:-

→ Charge of Magnesium ion = +2

→ Charge of ALUMINIUM ion = +3

→ Charge of Oxide ion = -2

Now, we KNOW that net charge of an ionic compound is always zero. So among the given options, the compound having net charge zero will be the ANSWER.

For Option (a):-

Net charge :-

= 2(+2) + 1(+3) + 4(-2)

= 4 + 3 - 8

= -1

For option (b):-

Net charge :-

= 1(+2) + 2(+3) + 4(-2)

= 2 + 6 - 8

= 0

For option (c):-

Net charge :-

= 1(+2) + 1(+3) + 4(-2)

= 2 + 3 - 8

= -3

For option (d):-

Net charge :-

= 4(+2) + 1(+3) + 4(-2)

= 8 + 3 - 8

= +3

________________________________

The net charge in MgAl₂O₄ is zero, so it is the required answer!

YOUR ANSWER IS THIS.

When soap is added to hard WATER, the Ca2+ and Mg2+ ions present in hard water react with soap. The sodium salts present in soaps are CONVERTED to their CORRESPONDING CALCIUM and magnesium salts which are precipitated as scum. The insoluble scum sticks on the clothes and so the cleaning capacity of soap is reduced.
