What are some salts that burn with a white flame?
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 flame, especially in the presence of a strong heat source.
3. **Strontium Salts**: Strontium compounds can emit a bright red flame but may also have a white appearance when mixed with other elements.
While specific compounds may produce various flame colors based on concentration and impurities, the key is that the presence of certain metal cations can influence the color of the flame produced. It's important to handle all chemicals safely and be aware that the flame's color can depend on a variety of conditions, including heat and oxidation states.
