The laboratory tech accidentally mixed NaHCO3 with BaCl2-2H2O instead of KCl when preparing unknown mixture for this experiment.
How would this mistake affect the calculated percentage of NaHCO3 in the mixture? Justify answer with an explanation.

Is it still possible to determine the percentage of NaHCO3 in the misture given the error made by the lab tech? Justify answer with an explanation.

  1. Again, I don't know how you're determining the NaHCO3. If you're titrating it with HCl I don't think there would be a difference. Although you the use of H2SO4 as a titrant would cause pptn of BaSO4 I think it could be done with H2SO4 also.
