Q1 of 25 Page 154

From the table given below, furnish your points of inference.

Solubility of any solute in a given solvent can be defined as grams of solute required to saturate 100g of solvent at a particular temperature. A saturated solution means no more solute can be dissolved in the given amount of solvent at a particular temperature.

So keeping in mind the above definitions, we can furnish following inferences:


•36g NaCl dissolves in 100g water to give a saturated solution at 25oC


•95g NaBr dissolves in 100g of water to give a saturated solution at 25oC


•184g NaI dissolves in 100g of water to give a saturated solution at 25oC


•NaI is more soluble in water than other two at 25oC since maximum grams of it are required to saturate 100g of water.
