Answer :
It will be both. It would be that answer because the sugar and salt will dissolve forming a solution, and the sugar will be a suspension and I think that the reaction will not be immpressive because when you mix water and salt it will be a weak acid and when you mix sugar and water it will concentrate at the end of the substance.
Answer;
It will be both
Explanation;
This is because the salt and sugar will dissolve forming a solution, the sand will form a suspension.
-A solution is a mixture that is made by dissolving a substance called solute in a solvent such as water. In this case salt and sugar dissolve in water to form a solution.
-A suspension is formed when particles, such as sand that are insoluble in a solvent and that are large in size, settle down after some time due to gravity. Therefore, in our case, sand is insoluble in water and thus forms a suspension with water.
