Question

Consider the unbalanced equation:. HC2H3O2 (aq) +Ba(OH)2 (aq) --> H2O (l) +Ba(C2H3O2)2 (aq). . balance the equation and determine how many moles of Ba(OH)2 are required to completely neutralize 0.461 mole of HC2H3O2.

Answer 1

The balanced chemical reaction is :

2HC2H3O2 (aq) +Ba(OH)2 (aq) --> 2H2O (l) +Ba(C2H3O2)2 (aq)

We are given the amount of HC2H3O2 to be used in the reaction. This will be the starting point for our calculations.

0.461 mol HC2H3O2 ( 1 mol Ba(OH)2 / 2 mol HC2H3O2) = 0.231 mol Ba(OH)2
