Question

HCl or h2so4r strong acid while their solution are equimolarr they have different pH value as calculate d in problem 10.2and 10.4 why they have different pH value?
​

Answer 1

Answer:

consider the calculation of pH of 0.1M HCl and 0.1MH2SO4

pH = -log(H+)

For HCl : pH = 1

For H2SO4 pH =1- log2 = 1- 0.3010 = 0.6990

Therefore H2SO4 has low pH than HCl.
