Cold water simply slows down the rate at which salt dissolves.

If you put salt in warm or cold water it dissolves better and faster than baking soda.

Yes, temperature can affect the amount of salt that dissolves in water. Generally, as temperature increases, the solubility of salt also increases, meaning that more salt can dissolve in water at higher temperatures.
Hot water typically consists of H2O molecules and salt. Cold water with salt is also made up of H2O molecules and dissolves the salt in its solution.
Rock salt dissolves fastest in hot water.
the hottter the temperature the faster salt dissolves
Factors that may affect the rate at which salt dissolves in water include temperature (higher temperatures generally increase the rate of dissolution), agitation or stirring of the solution (increases contact between salt and water molecules), surface area of the salt particles (finely ground salt dissolves faster), and the concentration of the salt solution (higher concentrations may slow down the dissolution rate).
When salt is added to water to change its color, the salt dissolves in the water and does not directly affect the color of the water.
