ANSWER:
Solution 60P:
Here, we are going to calculate the concentration of [OH-] ion from each solution.
Step 1:
Strong base is a base which can dissociate completely in aqueous solution. For example : NaOH, Ba(OH)2
NaOH(s) ------> Na+ (aq) + OH-(aq)
Therefore, NaOH solution does not have any intake NaOH. Therefore, the concentration of the OH- ion is same as the concentration of base.
