#1 How many grams of KNO 3 are needed to saturate 50. grams of water at 70 o. Saturated, on the curve. The quantity of water is not 50. grams, you must divide the solubility from table G by 2. At 70. DC 139. grams will saturate KNO 3 in 100.g of water. (70 DC, 139 g) Scale the solubility grams from the standard 100g of water on table G to the 50. grams asked for on the question. 139 = X X = about 69.5 grams

#2 How many grams of KClO 3 are needed to saturate 100. grams of water at 40 o. Saturated, on the curve. The quantity of water is 100, read from table G directly. At 40. DC about 16. grams will saturate KClO 3 in 100.g of water, that’s the answer! (40 DC, 16 g)

#3) How many grams of KClO 3 are needed to saturate 100. grams of water at 40 o. Saturated, on the curve. The quantity of water is 100, read from table G directly. At 40. DC about 16. grams will saturate KClO 3 in 100.g of water, that’s the answer! (40 DC, 16 g)

#4) A solution contains 14 g. of KCl in 100g of water at 40DC. What is the minimum amount of KCl needed to saturate the solution. Saturated, on the curve. The quantity of water is 100, read from table G directly. At 40. DC about 38 of KCl can dissolve, in 100g of water. (40 DC, 38 g) THE QUESTION INDICATED ONLY 14 GRAMS WAS DISSOLVED, HOWEVER 38 GRAMS CAN DISSOLVE, THEREFORE YOU NEED 24 MORE TO BRING THE 14 GRAMS TO SATURATION. (40 DC, 14 g) 24g\

#5) How many grams of NaNO 3 per 100g of water would produce a supersaturated solution? 100g of water, read directly off of table G. Look for a coordinate ABOVE the curve of sodium nitrate. (10DC, 60g)…UNSATURATED (20DC,800g)…UNSATURATED (30DC,90g)…UNSATURATED 40DC,110g) THESE COORDINATES ARE UNDER THE SODIUM NITRATE CURVE…UNSATURATEDC URVE, Ans..ABOVE CURVE…SUPERSATURATED

#7) A SOLUTION CONTAINS 90 GRAMS OF A DISSOLVED SALT IN 100g of WATER AT 40DC. Which is unsaturated. read directly off of table G. Look for a coordinate BELOW the curve of ONE OF THE SALTS.. (40DC,90g)…UNSATURATED FOR Sodium Nitrate, it is the only salt this coordinate is under. THIS COORDINATE is UNDER THE SODIUM NITRATE CURVE…UNSATURATEDC URVE,
