Explain solute-solvent interaction, saturated/unsaturated solutions, and define solution and its components.

Here are the solutions to your questions:

Section B: Short Questions

1. Explain the solute-solvent interaction to prepare sodium chloride solution.
When sodium chloride ($\text{NaCl}$), an ionic solute, is added to water ($\text{H}_2\text{O}$), a polar solvent, the water molecules surround the $\text{Na}^+$ and $\text{Cl}^-$ ions. The partially negative oxygen atoms of water are attracted to the positive $\text{Na}^+$ ions, while the partially positive hydrogen atoms are attracted to the negative $\text{Cl}^-$ ions. These ion-dipole interactions are strong enough to overcome the electrostatic forces holding the ions in the $\text{NaCl}$ crystal lattice, causing the salt to dissolve and the ions to become hydrated.

2. Differentiate between the saturated and unsaturated solution?
A saturated solution contains the maximum amount of solute that can be dissolved in a given amount of solvent at a specific temperature. If more solute is added, it will not dissolve and will settle at the bottom. An unsaturated solution, on the other hand, contains less solute than the maximum amount that can be dissolved at that temperature, meaning more solute can be added and will dissolve.

3. Define solution and explain the major components of solution?
A solution is a homogeneous mixture of two or more substances. The major components are the solute, which is the substance present in a smaller amount and dissolves, and the solvent, which is the substance present in a larger amount and does the dissolving.

4. What do you mean by mass/volume percent?
Mass/volume percent (\text{% m/v}) is a concentration unit that expresses the mass of solute in grams per 100 milliliters of solution. It is calculated as:

\text{% m/v} = \frac{\text{Mass of solute (g)}}{\text{Volume of solution (mL)}} \times 100\%
