Question

Calculate ph of solution obtained by diluting 25 ml of N/100 HCL to 500ml

Answer 1

The pH will be 3.40

Normality of HCl will be equal to Molarity as it's equivalent factor is 1

here is your solution

Answer 2

Normality=Molarity×equivalent factor

HCl has 1 equivalent factor

so it's Normality=Molarity
