What is a true statement with regard to 0 .10   M   H 2 SO 4 solution?
Options
- A[ H S O 4 - ] > [ H + ]
- B[ S O 4 2 - ] [ H + ]
- C[ H + ] > [ H S O 4 - ]
- D[ H 2 S O 4 ] > [ H + ]
Correct answer
C. [ H + ] > [ H S O 4 - ]
Step-by-step solution
H 2 S O 4 is a diprotic and in the first stage of ionization behaves as a strong acid, but in the second stage of ionization it behaves as weak acid. HSO 4 − → H 2 O H +   +   SO 4 2 − Thus, we also get some H + in the second stage. Hence, [ H + ] > [ H S O 4 - ]
