A student placed 50.00 mL of a water sample into an Erlenmeyer flask. Three
drops of K2CrO4 (aq) were then added to
the flask. The buret contained 0.080 M
AgNO3(aq) as the titrant. If 15.70 mL of
titrant was used to reach the end point,
calculate the amount of chloride ions in
mg/L found in the sample.
