When you have added as much solute as can dissolve in the solvent, the solution is called:
concentrated
supersaturated
saturated
unsaturated
Identify the solvent
dissolve more solute than you should be able to by heating the solution, then cooling
A student is preparing solutions for a laboratory experiment by dissolving solid solutes in liquid solvents. Which action will increase the rate of solubility
lowering the temperature of the solvent
stirring the solute in the solution
increasing the pressure on the solution
increasing the particle size of the solute
Since "like dissolves like", water and oil will not mix because
both of them are polar
both of them are nonpolar
oil is polar and water is nonpolar
oil is nonpolar and water is polar
What is the general trend of gas solubility with increasing temperature?
Solubility increases
Solubility decreases
Solubility remains constant
Solubility first increases then decreases
What happens to the solubility of a gas when the pressure above it is increased?
It increases
It decreases
It remains the same
It evaporates
Which of the following would result in being able to dissolve a greater amount of solid in a solution?
Lower the temperature.
Decrease the pressure of the solution.
Increase the pressure of the solution.
Heat the solution.
Explain the effect of surface area on the rate of dissolution.
Surface area has no effect on the rate of dissolution.
The rate of dissolution decreases with an increase in surface area.
The rate of dissolution increases with an increase in surface area.
The rate of dissolution remains constant regardless of surface area.
When no more solute dissolves the solution is _________
supersaturated
unsaturated
saturated
