Question

31. The enthalpies of neutralization of a weak bas
AOH and a strong base BOH by HCI are - 1225
cal/mol and - 13000 cal/mol respectively. Whe
one mole of HCl is added to a mixture containir
I mole of AOH and I mole of BOH, the enthal
change was - 12500 cal/mol. In what ratio ist
acid distribution between AOH and BOH?
(1) 2:1
(2) 2:3
(3) 12
(4) None of these​

Answer 1

Answer: A

Solution :

−12250x−13000(1−x)=−12500

750x=500⇒x=2/3 and y=1/3

So,  x/y = 2/1
