Which compound becomes less soluble in water as the temperature of the solution is increased?
red and pink
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
What liquid solution becomes red in an acid?
The Litmus solution becomes red when an acid is added in it.
What solution cannot dissolve any more solute under specified conditions?
A solution that does not allow any more solute to dissolve (at room temperature) is called a SATURATED SOLUTION. But a saturated solution can be made to dissolve more solute by heating it. Then it is called a super saturated solution.The solvent becomes saturated and the no more solute will disolve
A liquid cooled down below a certain temperature becomes a what?
it becomes solid.

What happenes to the solution temperature if the dissolving process is endothermic?
the solution becomes cool down as in case of glucose in water.
Which compound becomes less soluble in water as the temperature of the solution is increased?
red and pink
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.
How is salinity related to temperature?
The warmer a solution becomes, the higher the salinity can be. Warmer water can have more of a salt dissolved in it.

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.
What is the color of phenol red at acidic pH?
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
What happens to the solubility of calcium chloride if you chill the solution?
Since calcium chloride is an ionic salt, it becomes less soluble as the temperature lowers.
What liquid solution becomes red in an acid?
The Litmus solution becomes red when an acid is added in it.
Why does copper sulfate solution crystallize?
i am wondering why as well, someone please ANSWER! Are you talking about those crystal growing kits? If you are then what happens: as the water evaporates, the solution becomes more concentrated and finnaly the amount of the salt in solution exceeds the solubility for the the salt. The salt then falls out of solution. Using the anology- "like dissolves like, the CuSO4 crystals will nucleate upon themselves and othe salts will nucleate on themselves.... that is how you get different colors.
