Explanation:
If a solution contains 0.5 grams of NaCl and 100 grams of water, NaCl is the solute and water is the solvent.
<u>A) True
</u>
A solute is the substance that is dissolved in another medium which is the solvent. In this problem, the NaCl is the solute and the water is the solvent.
Question 2
In a solution, the solute is the substance in the smaller amount.
A) True
This is true. A solute is usually is lesser amount compared to the solvent.
Question 3
In a solution, the solvent is present in the larger amount.
A) True
The solvent is usually more in the solution. This is because during solvation, the solvent surrounds each particle of the solute and takes it into solution.
Question 4
A solution is saturated when it contains the maximum amount of solute for the given solvent.
A) True
A saturated solution is a solution in which no more solute can be dissolved further.
Question 5
Stirring a solution
A) increases the rate at which solute and solvent particles contact each other
Stirring increases the rate of solution by bringing the solute in contact with the solvent.
Question 6
Increasing the temperature of a solution will enable you to
A) dissolve more solute
The rate of dissolution increases by increase in temperature as the molecules gain more kinetic energy.
Question 7
Which of the following is the best definition of a mixture?
B) combination of two or more substances
A mixture is a combination of two or more substances. The substances are not chemically combined together.
