You question is very ambiguous. AgCl is the least soluble, Na2CO3 is the most soluble, CaSO4 & PbCl2 solubilities are in the same order of magnitude.
The salt calcium sulfate is sparingly soluble in water with a solubility of 0.209 g/100 mL of water at 30 degree C. If you stirred 0.550 g CaSO4, into 1.000 mL water at 30 degree C, what would the molarity of the resulting solution be? How many grams of CaSO4 would remain undissolved? The balanced equation for the oxidation of ethanol to acetic acid by potassium dichromate in an acidic aqueous solution is 3C2H5OH(aq) + 2 K2Cr2O7(aq) + 16HCl(aq) xrarr 3 CH3COOH(aq) + 4 CrCl,(aq) + 4 KCl(aq) + 11H2O(l) What volume of a 0.600 M potassium dichromate solution is needed to generate 0.166 mol acetic acid (CH3COOH) from a solution containing excess ethanol and HCl?
