What else can I help you with?
What would happen if you were to take a saturated solution at a certain temperature and cool it slowly?
the concentration of this solution is going to reduce.< Lets assume that the solution is comprised of water and salt> Then the water at a certain temperature begins to evaporate unlike the salt. at the end of the process, yes we agree that the solution has finally come to a room temperature, but concentration was lost during cooling. I mean that the solution becomes less concentrated
Why a saturated solution on heating becomes unsaturated explain and give example?
On heating a saturated solution it becomes unsaturated because heating causes kinetic energy to increase the distance between the molecules of liquid. Thus the solute takes free space present in the solvent. That is why saturates solution becomes unsaturated upon heating.
What happens with phenothalein is placed in Magnesium hydroxide?
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
How much solute can be dissolved before the solution becomes saturated?
The amount of solute that can be dissolved in a solvent before the solution becomes saturated depends on the solubility of the solute in that particular solvent at a given temperature. Once the solution reaches its maximum capacity to dissolve more solute, it becomes saturated and any additional solute will not dissolve.
Is chloroform a solid or a liquid?
Chloroform is a liquid, it becomes solid (freezes) at -63.5oC.
Copper is added to a solution of nitric acid. The solution becomes hot and changes from colorless to dark blue. What is the best explanation for the change in temperature?
in study island, the answer is "The reaction between the copper and the nitric acid produces heat. It is exothermic."
What happenes to the solution temperature if the dissolving process is endothermic?
the solution becomes cool down as in case of glucose in water.
What compound becomes less soluble in water as the temperature of the solution is increased?
This compound is the cerium sulfate.
Is steel a liquid solution?
At a certain temperature, Steel becomes liquid. And I suppose it is even a solution as Steel is an alloy of metals, Not only Iron alone.

Is helium a vapor?
Yes, helium is a colorless, odorless, and tasteless gas at room temperature. It only becomes a liquid when cooled to extremely low temperatures (-268.9°C).
Why a saturated solution on heating becomes unsaturated explain and give example?
On heating a saturated solution it becomes unsaturated because heating causes kinetic energy to increase the distance between the molecules of liquid. Thus the solute takes free space present in the solvent. That is why saturates solution becomes unsaturated upon heating.
What color is bromine water and NaCl mixed together?
Bromine water and NaCl mixed together appears colourless. The only condition which there is a colour is when the bromine water is old (bromine water is basically rum), but under normal conditions, the mixture ought to be colourless.

Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.

Why molality is not temperature dependent?
Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.
Is chloroform a solid or a liquid?
Chloroform is a liquid, it becomes solid (freezes) at -63.5oC.
