Question

Which solution will ionize less than it does in pure water?

Answer 1

Answer:

To Determine: The solution in which the ionize less than it does in pure water.Answer: In solution ionize less than it does in pure water. Therefore, option (d) is correct.Explanation:ionizes into its constituent ions as follows, is a strong electrolyte and thus dissociates completely in water into sodium and nitrite ions as follows,In presence of , there will be excess of common ions in the solution. According to Le-Chaterliers’s principle, the reaction equilibrium will move towards the left. Suppression of ionization of weak electrolyte in presence of a strong electrolyteis known as common ion effect. In solution ionize less than it does in pure water.

Answer 2

Answer:

In which of these solutions will HNO2 ionize less than it does in pure water?

a. 0.10 M NaCl

b. 0.10 M KNO3

c. 0.10 M NaOH

d. 0.10 M NaNO2

Correct option is d.
