Here are the answers to question 2: a) Solubility is the maximum mass of a solute that can dissolve in a given mass or volume of a solvent at a specific temperature to form a saturated solution. b) Two factors that affect the solubility of a solid in a liquid are: Temperature The nature of the solute and solvent c) Step 1: Measure out exactly 100 cm³ of water using a measuring cylinder and pour it into a beaker. Step 2: Maintain the water at the specified temperature using a water bath or other temperature control method. Step 3: Add the salt gradually to the water while stirring continuously until no more salt dissolves and a small amount of undissolved salt remains at the bottom of the beaker. Step 4: Carefully filter the saturated solution to separate the undissolved salt. Step 5: Transfer the filtered solution to a pre-weighed evaporating dish and gently heat it to evaporate all the water. Step 6: Allow the evaporating dish and the remaining dry salt to cool, then weigh it. The mass of the dry salt obtained is the mass of salt that dissolved in 100 cm³ of water at the given temperature. d) You would know that the solution is saturated when, after adding more salt and stirring, some undissolved salt remains at the bottom of the container. e) One use of the information obtained from this experiment is in industrial processes, such as the purification of chemicals through crystallization or the production of various solutions with specific concentrations.
