`CaCI_(2)` is added to NaCI in the electrolytic manufacture of sodium.

Explanation

To solve the question regarding the addition of \( \text{CaCl}_2 \) to \( \text{NaCl} \) in the electrolytic manufacture of sodium, we can break down the explanation into clear steps:

### Step 1: Understand the Purpose of Adding \( \text{CaCl}_2 \)
The primary reason for adding \( \text{CaCl}_2 \) to \( \text{NaCl} \) is to lower the melting point of the mixture. The melting point of pure \( \text{NaCl} \) is approximately 1080 K, which is relatively high for electrolysis.

**Hint:** Consider why a lower melting point is beneficial for the electrolysis process.

### Step 2: Identify the New Melting Point
