Question

Determine how many moles of Ba(OH)2 are required to completely neutralize 0.117 mole of HC2H3O2.

Answer 1

HC₂H₃O₂ (CH₃COOH) - acetic acid
-------------------------------------------------
2CH₃COOH + Ba(OH)₂ ----> (CH₃COO)₂Ba + 2H₂O
2 mol              1 mol

2 mol CH₃COOH -------- 1 mol Ba(OH)₂
0,117 mol CH₃COOH ------ X
X = 0,117/2
X = 0,0585 mol  Ba(OH)₂
