You are using gravimetric analysis to determine the concentration of calcium (Ca2+) in tap water. The calcium is precipitated as calcium oxalate monohydrate upon addition of ammonium oxalate to the tap water according to the following reaction: Ca +2 (aq) + C2O4 -2 (aq) → CaC2O4 ∙H_2 O (s) Ksp = 1.3 x 10 -8 The protocol calls for addition of 25 mL of 1.0 M ammonium oxalate to 25 mL sample. In order to ascertain the accuracy of your...
