Question:

The chloride in an aqueous sample of BaCl2 is precipitated with 50.0 mL of 0.100 M AgNO3. The excess silver nitrate is titrated with 17.0 mL of 0.125 M K2CrO4. Calculate the mass of the barium chloride in the sample.

BaCl(aq) 2 AgNO3(aq) + 2 AgNO3(aq) 2 AgCl(s) + Ba(NO3)2(aq) + KCrO4(aq)  AgCrO4(s) + 2 KNO3(aq)
