WebA solution is prepared by mixing 34.45 grams of mercury (II) cyanide and 310. grams of water at 20 degrees Celsius. Use the solubility information that is presented in Table 7.9.1 to determine whether the resultant solution is saturated or unsaturated, and calculate the amount of excess solute that remains undissolved in this solution. Answer WebThe Solubility Rules 1. The nitrates, chlorates, and acetates of all metals are soluble in water. Silver acetate is sparingly soluble. 2. All sodium, potassium, and ammonium salts are soluble in water. 3. The chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. HgI2 is insoluble in
