No, mixing salt and sugar does not result in a chemical reaction.
When you combine salt (sodium chloride) and sugar (sucrose), you are simply creating a mixture of two different substances. Both salt and sugar retain their individual properties and can be separated from each other by physical means, such as dissolving in water or filtering. A chemical reaction would involve a change in the chemical structure of one or both substances, resulting in the formation of new substances with different properties.
In essence, while mixing salt and sugar creates a combined form that’s different from each separately, it does not lead to any chemical change; therefore, it is not a chemical reaction.
