The changes that indicate that the powder being examined is baking soda are:
- Formation of bubbles or foaming: When baking soda reacts with vinegar, it produces carbon dioxide gas, which leads to the formation of bubbles or foaming.
- Constant color: Baking soda is a white powder, and its color remains constant before and after reacting with vinegar. Therefore, if there is no change in color, it indicates that the powder being examined is baking soda.
Note: Formation of crystals is not a specific indicator for baking soda, as it can be observed with other substances as well.
