Salts that produce a white flame when burned typically contain metal ions that, upon heating, emit a bright white light. Here are a few examples:
1. **Barium Salts**: Barium compounds, particularly barium chloride (BaCl2), can produce a bright white flame or a greenish-white flame in certain conditions.
2. **Calcium Salts**: Calcium compounds, such as calcium chloride (CaCl2) or calcium carbonate (CaCO3), can burn with a bright orange to white
