deep pink colour is given to flame by the salts of

Options

A. Strontium
B. Potassium
C. Zinc
D. Barium

Explanation

To determine which salts produce a deep pink color in a flame test, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Flame Tests**: Flame tests are used to identify the presence of certain metal ions based on the color they emit when heated in a flame. Different metal ions produce characteristic colors.

2. **Identifying the Color**: The question specifies a "deep pink" color. We need to recall which metal salts are known to produce this specific color during a flame test.

3. **Common Metal Salts and Their Flame Colors**:
- **Strontium Salts**: Strontium compounds, such as strontium carbonate (SrCO₃) or strontium nitrate (Sr(NO₃)₂), are known to produce a deep pink or red flame.
- **Potassium Salts**: Potassium salts typically produce a lilac or light purple flame.
- **Barium Salts**: Barium salts produce an apple green flame.
- **Zinc Salts**: Zinc salts do not produce a significant color and are often colorless in flame tests.

4. **Conclusion**: Based on the information gathered, strontium salts are responsible for producing a deep pink color in flame tests.

5. **Final Answer**: The salts that give a deep pink color to the flame are the salts of **Strontium**.
