Dear student as we can see both of the given solutions are acidic in nature so [H+] = 10^-5 and 10^-4 mole/lit. Now normality = [H+], So by applying normality equation I.e. Nr= (N1V1+N2V2)/(V1+V2) we get Nr 7*10^-5.Taking -log both sides we get -log(7*10^-5) and that is equal to 4.15 hope it helps. Please approve it 😊😊
