Question

classify the physical and chemical change from the following:e)adding salt into the water​

Answer 1

Step-by-step explanation:

This is a physical change because the original substances can be recovered by evaporation. In chemical change substances cannot be recovered.

Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion). Thus, any ionic compound that is soluble in water would experience a chemical change.

Answer 2

Step-by-step explanation:

Dissolving salt in water, is a physical change because only the state of the matter has changed. Physical changes can often be reversed. Allowing the water to evaporate will return the salt to a solid state. ... It has not combined with the water to cause a chemical reaction.
