Question

13. How is concentration of hydroxide ions (OH) affected when excess base is
dissolved in a solution of sodium hydroxide?​

Answer 1

Answer:

When an excess base is dissolved in a solution of sodium hydroxide. Sodium hydroxide dissociates into OH- ions and when the number of OH- increases then concentration also increases because concentration is the number of OH- ions present per unit volume.

Answer 2

Answer:

When an excess base is dissolved in a solution of sodium hydroxide. Sodium hydroxide dissociates into OH- ions and when the number of OH- increases then concentration also increases because concentration is the number of OH- ions present per unit volume
