How many moles of KOH are required to neutralize 2.4 mol of H2SO4?

Question

a) 1.2
b) 2.4
c) 3.6
d) 4.8

Answer 1

For each mole or acid, 2 moles of H+ are produced: 2 moles of KOH are needed. Then answer is d)

Answer 2

d) 4.8 Sulfuric acid is diprotic, meaning that it provides 2 hydrogen ions per molecule. Potassium hydroxide is monobasic, so it will take twice as many moles of it to neutralize the acid.
