In which solvent NaCl has maximum solubility ?

Options

A. `H_2O`
B. `C_2H_5OH`
C. `CH_3COCH_3`
D. `C_2H_5OC_2H_5`

Answer

To determine in which solvent NaCl has maximum solubility, we can follow these steps:

### Step 1: Understand the nature of NaCl
NaCl (sodium chloride) is an ionic compound. It dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻) when dissolved in a solvent.

**Hint:** Remember that ionic compounds dissociate into their respective ions in a solvent.

### Step 2: Identify the properties of NaCl
NaCl is a strong electrolyte, meaning it completely dissociates into ions in solution. This property is crucial for understanding its solubility in different solvents.

**Hint:** Strong electrolytes fully dissociate in solution, which is important for solubility.

### Step 3: Consider the principle of solubility
The principle of solubility states that "like dissolves like." This means that polar solutes tend to dissolve well in polar solvents, while non-polar solutes dissolve better in non-polar solvents.

**Hint:** Use the "like dissolves like" principle to determine solubility compatibility.

### Step 4: Evaluate the solvents provided
The solvents listed are:
1. Water
2. Ethanol (an alcohol)
3. Acetone (a ketone)
4. Diethyl ether

Among these, we need to assess their polarity. Water is known to be a highly polar solvent, while ethanol, acetone, and diethyl ether are less polar compared to water.

**Hint:** Compare the polarity of each solvent to determine which one is the most polar.

### Step 5: Determine the most suitable solvent for NaCl
Since NaCl is a polar ionic compound, it will dissolve best in the most polar solvent available. Water, being the most polar solvent among the options, will provide the best environment for NaCl to dissociate and dissolve.

**Hint:** Identify which solvent has the highest polarity to maximize solubility.

### Conclusion
Therefore, the solvent in which NaCl has maximum solubility is **water**.

**Final Answer:** Water (Option 1)
