g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution. Raising the temperature of the solution by 20°C would not affect the solution...
