Answer 1

NH4Cl is the solute and H2O is the solvent and the correct statement is: NH4Cl is the solute, and the solution is unsaturated.

Step-by-step explanation:

The correct statement is:

NH4Cl is the solute, and the solution is unsaturated.

Here's why:

Solute vs. solvent: In a solution, the component present in a smaller amount is called the solute, while the component present in a larger amount is called the solvent. In this case, 45 grams of NH4Cl are dissolved in 100 grams of H2O, so NH4Cl is the solute and H2O is the solvent.

Saturated vs. unsaturated: A saturated solution is one in which no more solute can be dissolved at a given temperature. An unsaturated solution can still dissolve more solute.

Reasoning:

The solubility of ammonium chloride (NH4Cl) in water at 70°C is approximately 57 grams per 100 grams of water. Since only 45 grams of NH4Cl are dissolved in 100 grams of water, the solution is not yet saturated. It could still dissolve up to 12 grams more of NH4Cl before becoming saturated.

Therefore, the most accurate statement is that NH4Cl is the solute in an unsaturated solution.

Answer 2

NH4Cl is the solute, and the solution is unsaturated.

Step-by-step explanation:

To create a saturated solution of ammonium chloride at 70°C, we need to dissolve 62 g of ammonium chloride in 100 g of water.

The question tells us that 45 grams of NH4Cl was dissolved in 100 grams of H20 at 70°C. This creates an unsaturated solution since the amount of solute present is less than the amount of solute that the NH4Cl solution can normally hold at 70°C.

Hence, NH4Cl is the solute, and the solution is unsaturated.
