Question

Which of the following salt produce an alkaline solution while dissolving in water :
( Nh4CL, Na2so4, na2co3 , NaNo2

Answer 1

Answer:Na2so4

Explanation:

Answer 2

Hey Dear,

● Answer -

Na2CO3 and NaNO2

● Explanation -

Strong of strong base and weak acid produces basic salt. When basic salt is dissolved in water, it produces alkaline solution.

Na2CO3 is a salt of NaOH (strong base) and H2CO3 (weak acid). Thus it will form alkaline solution in water.

2NaOH + H2CO3 --> Na2CO3 + 2H2O

NaNO2 is a salt of NaOH (strong base) and HNO2 (weak acid). Thus it will form alkaline solution in water.

NaOH + HNO2 --> NaNO2 + H2O

Hope this helps you.
