Question

Follow these steps:

Carefully measure out 3 Tablespoons of cold water into the jar.

Now measure out 1/8 teaspoon of salt and put it into the jar with the water. Put the lid on the container and shake it. Keep shaking until the salt is completely dissolved. To determine whether it has completely dissolved, hold the container up to the light and look carefully at the bottom, or open the lid and look into it. If you see little grains of salt there, it is not completely dissolved, so keep shaking until it looks the same each time you look.

If the salt does not dissolve completely after five minutes of vigorous shaking, write this in your notebook and go on to step 4. If the salt dissolves completely, add another 1/8 teaspoon of salt and repeat the process. Repeat over and over, keeping track of how many 1/8 teaspoons you add. Stop when you can’t get the salt to dissolve no matter how hard or long you shake the container.

Record how much salt you were able to dissolve in the 3 Tablespoons of water in the solubility data table.

Repeat steps 1-4, but this time using very warm or hot water. Before you do it, run the jar under hot water to warm it up so the water doesn’t cool off right away. Be sure to use the same amounts of water and salt as you did the first time. The only variable should be the temperature of the water.

Record your results, and then compare them with your previous results.
Were there any differences in the amount of salt that dissolved in the warm water versus the cold water?

Answer 1

Alot of salt dissolved in warm water than in cold water

Step-by-step explanation:

This is because cold water does not dissolve alot of salt and hot water dissolves alot of salt because of the kinetic energy acting on the liquid
