  1. 1. Name_______________________________________________ Group ______________Date ________________________________________________ List # _________________ Solubility 1.- The solubility of NH4Cl is 46 grams in 100 grams of water at 40°C. How much NH4Cl can dissolve in 500 grams of water at 40°C? __________________________________________ 2.- A solution of KClO3, has 20 grams of the salt in 100 g of water at 70 C. Approximately how many more grams of the salt can be added to the solution before reaching saturation point? a) 10 g b) 30 g c) 60 g d) 80 g3.- Which salt is least soluble at 0 C?a)KClO3 b)K2Cr2O7 c)KNO3 d)Ce2(SO4)34.- A beaker containing 80 g of Pb(NO3)2 in 100 g of water has a temperature of 30 C.Approximately how many grams of the salt are undissolved, on the bottom of thebeaker?a)14 g b) 20 g c) 66 g d) 80 g5.- When 20 grams of potassium chlorate, KClO3, is dissolved in 100 grams of water at 80ºC, the solution can be correctly described as:a) saturated b) unsaturated6.- Salts that contain at least one of the following ions will always be soluble in water.a) NO3-, Na+, K+ b) Mg2+, NO3-, Li+c) Na+, Li+, Sr2+ d) Na+, K+, Cl-, NO3-7.- Which compound will be soluble in water?a) K2S b) Fe(NO3)2 c) NH4Br d) All of the above are soluble in water.8.- Which compound will be insoluble in water?a)CuS b)Ag2SO4 c)AgBr d)Ca(OH)29.- True or false: All salts containing Cl- and Br- are soluble.10.- True or false: All salts containing SO4 -2 are soluble.
