The pH of the diluted base will always be between 7 and 8.
The first thing to remember that after dilution the nature of acid doesn’t change. If it is acid then it will remain that and same for the base.
Here, Initial OH– ion concentration = 5 x 10-5M = n/v
[where n and v number of moles and volume respectively denotes molarity]
After the initial solution is diluted, its volume will be 100 ⋅ V.
after dilution it will be 5 x 10-7M then p[OH] will be less than 7.
thus its pH will be slightly more than 7.
