How can you separate baking soda and salt?

There are a few different ways to separate baking soda and salt. One way is to dissolve the mixture in water, then filter the solution through a coffee filter. The baking soda will dissolve in the water, while the salt will be trapped in the filter.

Another way to separate baking soda and salt is to use a process called sublimation. Sublimation is the process of converting a solid directly into a gas, without passing through the liquid phase. To sublime baking soda, you can heat it to a temperature of about 500 degrees Celsius. The baking soda will vaporize, and the salt will be left behind.

Finally, you can also separate baking soda and salt by using gravity. If you let the mixture sit in a container, the heavier salt will sink to the bottom, while the lighter baking soda will float to the top. You can then skim the baking soda off the top of the container.
