Question #114484
How many moles of Ba(OH)2 would it take to neutralize 0.9 mole of hydrochloric acid?
Expert's answer
The neutralization reaction can be defined as following:
Ba(OH)2 + 2HCl = BaCl2 + 2H2O
As 1 mol of Ba(OH)2 is required neutralize 2 mol of HCl, then:
n(Ba(OH)2) = 0.9 mol × 1 mol / 2 mol = 0.45 mol of Ba(OH)2 is required to neutralize 0.9 mol of HCl.
Answer: 0.45 mol
