Frankly, it makes no sense. If he accidently spilled XXX into something,why would be be calculating the percentage of XXX? It shouldn't be there at all.

I think what you mean is the unknown is supposed to be a mixture of NaHCO3 and KCl but instead it is a mixture of NaHCO3 and BaCl2.2H2O. It won't make any difference if you are determining NaHCO3 by titration with an acid.
