The enthalpies of neutralization of a weak base AOH and a strong base BOH by HCI are –12250 cal/ mol and –13000 cal/ mol respectively. When one mole of HCI is added to a solution containing 1 mole of AOH and 1 mole of BOH, the enthalpy change was –12500 cal/ mol. In what ratio the acid is distributed between AOH and BOH?
A
2 : 1
B
2 : 3
C
1 : 2
D
None of these
Answer
2 : 1
Explanation
Solution
–12250x –13000 (1 – x) = –12500
750 x = 500 Ž x = 2/3
So, required ratio is =12
