A chemist performed an experiment in which silver nitrate was used to precipitate all of the chromate ion as silver chromate, Ag2CrO4 from 200 mL of a solution of potassium chromate, K2CrO4. This process required 120 mL of 0.200 M AgNO3.

Question

A chemist performed an experiment in which silver nitrate was used to precipitate all of the chromate ion as silver chromate, Ag2CrO4 from 200 mL of a solution of potassium chromate, K2CrO4.  This process required 120 mL of 0.200 M AgNO3.

Write the balanced equation that describes this process

DrBob222 · Answer

AgNO3 + K2CrO4 --> Ag2CrO4 + KNO3 You balance it.
