How long does it take baking soda mixed into water to freeze?

The freezing time for a baking soda and water mixture can vary based on several factors, including the concentration of baking soda, the temperature of the water, and the freezer settings. Generally, a solution with a moderate amount of baking soda may take longer to freeze than plain water due to the lower freezing point of the solution. On average, it could take anywhere from 2 to 4 hours for such a mixture to fully freeze. It's advisable to check periodically to determine the exact freezing time.
