Question

Calculate the ph of 0.2m H2So4

Answer 1

H2SO4 is a strong polyprotic acid. It undergoes 2 deprotonations, only one of which is complete. They are as follows:

H2SO4(aq)+H2O(l)→H3O+(aq)+HSO4−(aq)

Answer 2

Since H2SO4 is a strong acid we can assume 100℅ dissociation. Therefore, in a 0.1 M H2SO4 solution we will have 0.2 mol/L of H+ions we can exprees 0.2 as

2×10^-1

I hope it help you
