Yes; the solubility of solids in liquids decrease when the temperature decrease.

A solution may be prepared by dissolving crystals of a salt in water What would probably not affect the rate of solubility?
Reducing Aire Pressure
How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
Why the collected crystals in a recrystallization are washed with cold water rather than warm water?
Warm water would make your crystals go into solution again
What Word would you use to descirbe sugar dissolving into water?
The Process Is called solution
Why is it that the sugar crystals disappear when stirred in water?
The sugar crystals have no added colour and are 'white' crystals in appearance. Once dissolved into the water, they create a transparent sugary solution. The same is for salt crystals that create a saline solution.

Do you need a 9volt battery to make a crystal?
No. You can make a crystal by dissolving something such as salt into hot water until no more will dissolve, and then cooling the solution. Or by dissolving something such as salt into water and gradually evaporating the water away, or by cooling a liquid , or a vapour below its triple point.

How do you make saturated solution of salt?
Add salt to water until it stops dissolving and undissolved crystals settle to the bottom of the container. The amount of salt required to reach saturation will depend on the temperature of the water. Warmer water will hold more salt in solution.
What makes the crystals grow in rock candy?
It's easy to grow your own sugar crystals! Sugar crystals are also known as rock candy since the crystallized sucrose (table sugar) resembles rock crystals and because you can eat your finished product. You can grow beautiful clear sugar crystals with sugar and water or you can add food coloring to get colored crystals. It's simple, safe, and fun. Boiling water is required to dissolve the sugar, so adult supervision is recommended for this project.

Does the temperature of water affect how fast salt crystals or sugar crystals melt?
Yes. (BTW, the crystals are dissolving, not melting...melting occurs at a very high temperature).
Is salt mix in water a saturated solution?
When you first mix the salt into the solution the salt will dissolve into the water. As you keep on pouring more salt into the water eventually the salt will stop dissolving and once the salt stops dissolving the solution is then saturated.
Do water and salt mixed together make crystals?
When mixed, it is a solution. If left to sit, the salt can partially distill out of the solution. If the water is left to evaporate, there will be crystals.

What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
The molarity of a solution made by dissolving 23,4 g of sodium sulphate in enough water to make up a 125 mL solution is 1,318.
