Question

50ml of 0.2M NaOH + 50 ml 0.1M H2SO4 find ph

Answer 1

Hey, there!

Here's the answer to the question.

Normality = Molarity × n-factor.

and

number of equivalence = Normality × volume

➡️ n factor for NaOH is 1 and for H2SO4 is 2.

(Now, refer to the attachment)

Conclusion: Since, the number of equivalence of both acid and base is same, they completely react to form salt. For this, the solution becomes neutral, i.e., pH = 7

Hope that helps.

Thanks.
