Baking soda, or bicarbonate of soda, is a strong leavening agent used in recipes that contain acids like vinegar or lemon juice. Baking soda reacts with liquid ingredients to produce carbon dioxide gas, which will make a baked good rise. Dry ingredients have a limited shelf life. You may find that when you try to use baking soda after it has expired, it is caked together and has reduced leavening power. Baking soda usually comes in a box, and you may need to use other containers to store it properly. This article will tell you how to properly store baking soda.

Always test by smelling and feeling the texture of the bicarbonate of soda before using to see if it is still fresh.
Using wet or contaminated utensils will activate the baking soda and reduce its shelf life.

Tips

Baking powder has different storage requirements than baking soda. It should also be sealed well and placed in a cool dry place. After the package is opened, it will last for approximately 6 months.

Thanks
