Answer to Question #114484 in Chemistry for tristan

Question

How many moles of Ba(OH)2 would it take to neutralize 0.9 mole of hydrochloric acid?

Answer 1

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
