How did increasing the temperature of the solvent change the rate at which copper sulfate dissolved in water?

the temperature acted as a catalyst and excited the atoms in the solvent to make it so that they were able to pick up the valence electrons that created the bonds in the copper sulfate faster

What color is a dissolved sulfate ion?
Colorless.
What purpose does a 1 cm layer of anhydrous sodium sulfate in the apex of the funnel serve while transferring the dichloromethane extract into the round-bottom flask?
Anhydrous sodium sulfate is used as a drying agent to remove microscopic amounts of dissolved water in a solvent. It works by chemically reacting with the water by forming its hydrate, which is insoluble preferably in the solvent in this case dichloromethane. This allows one to filter off the crystals containing the water that would otherwise have remained dissolved in the dcm.
What state is ammonium sulfate?
At standard temperature and pressure, ammonium sulfate is a solid.
At what temperature does liquid aluminum sulfate crystallize?
at room temperature
What is the state of matter of Copper 2 Sulfate at room temperature?
Copper Sulphate is a powder at room temperature, therefore it is a solid.
Will the products of copper sulfate and zinc nitrate which are copper nitrate and zinc sulfate release a gas?
Not under conditions of normal temperature and pressure, because the reactants and products are all solid, or in practice more often all dissolved in a solvent, and stable under such conditions
What would happen to the crystallization temperature if you boil the solution?
Temperature of a solution is a condition that controls the solubility of solute in a solvent. Take copper sulfate for example. At 100° Celsius (C) 203.3 grams (g) can be dissolved in 100ml of water; at 0° C, only 31.6g can be dissolved in water. If you continue to boil the solvent (water) away, the copper sulfate will come out of solution because the amount of water is lessened creating a supersaturated state that forces the solute out of the solution (in other words, the lesser amount of liquid water can't hold that much copper sulfate in solution.) Removing the heat source and allowing the solution to cool has the same effect. As it cools,the copper sulfate will come out of solution. So, basically, concentration of the solute at a given temperature is the controlling factor. Boiling off the solvent increases the concentration; cooling the solvent decreases the concentration the solvent can hold. Both ways create a state of supersaturation leading to crystallization at all the temperatures in the given range.
for which substance does temperature seem to have the greatest influence on solubility?
cerium sulfate
What color is a dissolved sulfate ion?
Colorless.
What is a mixture of a solute and a solvent?
A mixture of a solute and a slovent will create a solution. If we combine salt and water, the salt (the solute) will dissolve in the water (the solvent) to form that solution. Note that a mixture is different from a solution in that in a mixture, the two substance remain distinct, like with sand and water.
What happens to the density of water when copper sulfate is dissolved in it?
In general when you dissolve something in water the density of the solution will be greater than the density of the original water. This is because the solute (in this case, copper sulfate) will take up space between the water molecules, increasing the mass of the solution without increasing the volume. The density is calculated as mass divided by volume, so increasing the mass without increasing the volume will increase the density.

What is the solute in aqueous solutions?
Sugar is dissolved by the water, so therefore water is the solvent.
Will the rate of dissolving of Ce SO4 2 too decrease?
Cerium sulfate is a very strange compound; increasing the temperature the solubility decrease.
Name the solute and the solvent in a copper sulfate solution?
water
How temperature affects the solubility of sodium sulfate?
As temperature increase the solubility of sodium sulfate decrease
