Equilibrium Question 50
Question: $ 1\times {10^{-12}} $ of $ 1MH_2SO_4 $ will completely neutralise
Options:
A) $ 10ml $ of $ 1MNaOH $ solution
B) $ 10ml $ of $ 2MNaOH $ solution
C) $ 5ml $ of $ 2MKOH $ solution
D) $ 5ml $ of $ 1MNa_2CO_3 $ solution
Show Answer
Answer:
Correct Answer: B
Solution:
$ H_2SO_4+2H_2O $ ⇌ $ 2H_3{O^{+}}+SO_4^{-,-} $ NaOH ⇌ $ N{a^{+}}+O{H^{-}} $ 1 mole of $ H_2SO_4 $ acid gives 2 moles of $ H_3{O^{+}} $ ions. So 2 moles of $ O{H^{-}} $ are required for complete neutralization.
