If the standard solutions had been unknowingly been made up to be .0024M AgNO3 and .004M K2CrO4, would this have affected the results? And How?

1 Answer

  • 2AgNO3 + K2CrO4 ==> Ag2CrO4(s) + 2KNO3

    Hence, by mixing .0024M AgNO3 and .004M K2CrO4, you would have Ag2CrO4 precipitated out and left you with 0.0024M KNO3 mixed with (0.004-0.0024/2)M, or 0.0028M, of K2CrO4.
