What hypothesis can I use for salt dissolving faster in water than baking soda?

Hypothesis:

If the surface area of salt is increased, then the rate at which it dissolves in water will increase.

Reasoning:

The rate of dissolution is influenced by the surface area of the solute exposed to the solvent. By increasing the surface area of salt, more salt particles will be in contact with water molecules, allowing for faster dissolution. Baking soda has a larger particle size compared to salt, which means it has a smaller surface area. Therefore, salt is expected to dissolve faster than baking soda in water.
