What dissolves hardened baking soda?

Hardened baking soda, also known as sodium bicarbonate, can be difficult to dissolve. Here's why and how to address it:

Why it Hardens:

* Moisture: Baking soda absorbs moisture from the air, which causes it to clump and harden.

* Heat: Exposure to heat can also contribute to hardening.

How to Dissolve It:

1. Break it Up: Start by breaking up the hardened clumps into smaller pieces. You can use a spoon, fork, or even a mortar and pestle.

2. Add Water: Gradually add a small amount of water to the broken-up baking soda. Stir constantly to help dissolve the clumps. You may need to add more water as you go.

3. Heat: If the baking soda is still clumpy, you can try gently heating it. Place the baking soda in a saucepan over low heat and stir constantly. Do not let the baking soda burn.

4. Vinegar: While not dissolving it, vinegar will react with baking soda, creating carbon dioxide bubbles. This can help to break up the hardened clumps. Important: Do this in a well-ventilated area as it produces a strong fizzy reaction.

Prevention:

* Store Properly: Keep baking soda in an airtight container in a cool, dry place.

* Don't Overheat: Avoid storing baking soda near heat sources like ovens or stoves.

Alternatives:

* Buy a Fresh Batch: If the hardened baking soda is beyond repair, it's best to simply buy a new container.

Remember, if the baking soda has become contaminated or has a strong odor, it's best to discard it and start fresh.
