Question

A solution of potassium chlorate has 20 grams of the salt dissolved in 100 grams of water at 70 degrees Celsius. Approximately how many more grams of the salt can be added to the solution before reaching the saturation point?

Answer 1

NaNO3 K2Cr2O7 KNO3 CaCl2 Solubility (g of salt in 100 g H,O) Pb(NO3)2 KC NaCl KCO3 Ce2(SO4)3 0 10 20 30 40 50 60 70 80 90 100 Temperature (°C)

Answer:- To solve this, let's Curve graph. look above s The curve for Koloz is the line & according to at the 70°c Vertical cline, ci saturated solution of kelog contains 3og in 100 g H₂O Therefore, The question says there care 209 kelog dissolved which means, 30g - 209 = 109 kelo, solution is can further dissolve before the Saturated
