An equal amount of salt in hot and cold water dissolves at about the same speed. In chemistry, it results in a solution, as the ionic bond of NaCl is pulled apart by the attraction of Na to the O of H2O and the attraction of Cl to the H of H2O. That is the time the solution will be saturated. You need to define your parameters a little more carefully to get specific details. Materials for the Demonstration. If you choose to do the demonstration, follow the procedure below. Hot water makes little difference as the solubility of NaCl doesn't increase much with temperature (see wIki solubility table). Project the image Hot and Cold Water Dissolve Salt vs. Sugar. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster. How does water dissolve salts?

Making the solute dissolve faster . Salt is made up of a sodium molecules and chlorine molecules. Discussion: Salt would dissolve quicker in hot water because the molecules in hot water move faster than cold water because of the higher energy, therefore the molecules of hot water move fast, they can more easily break apart the other molecules of a different substance when they come into contact. constants the things i will keep is 1 skittle per cup in regular and salt water The control in your experiment will be water. When the solvent is warmed, the tiny particles it is made of move faster. Results: The salt dissolved quicker in hot water. Answer (1 of 5): Salt would dissolve better in hot water because, when substances have a high temperature, they have more energy. Question to Investigate. Grinding or crushing the solute increases the area of it which is exposed to the solvent. Let’s take this knowledge further and consider how quickly each substance .
