Answered by maham237 @ 23/12/2020

The answer to this question would be: 0.050 m

In this question, you have a 0.025m concentration of K2CO3 or potassium carbonate solution. The compound will dissociate into 2 K+ and 1 (CO3)2-

Then the amount of K+ ion in this solution assuming complete dissociation should be: 2/1 * 0.025m= 0.050m
