potassium chromate solubility

Solubility

Solubility Equilibria Discussions of solubility equilibria are based on the following assumption: When solids dissolve in water they dissociate to give the elementary particles from which they are formed Thus molecular solids dissociate to give individual molecules H 2 O: C 12 H 22 O 11 (s) C 12 H 22 O 11 (aq) and ionic solids dissociate to give solutions of the positive and negative

DETERMINATION OF THE Ksp OF Ag2CrO4

Prepare three samples of solid silver chromate by mixing ~6 mL of 4 00 mM silver nitrate and ~4 mL of 2 40 mM potassium chromate in separate large test tubes Mixing these should produce a suspension of red solid Cover a rubber stopper with parafilm so it will not contact the solution This will prevent contamination by chemicals leached from the stopper Stopper each test tube and shake them

recrystallization

According to Wikipedia the solubility of Potassium Dichromate increases very significantly with the temperature At 20C 13g/100ml and at 100C 104g/100ml Therefore it should be possible to dissolve about 520g of potassium dichromate in 500 ml of boiling water but only about 65g in the same water but at room temperature
