Answer;
Solvent
Explanation;
-A solution is a homogeneous mixture that is made of two or more substances. In other words, It is a mixture in which one of the substances dissolves in the other. The substance which dissolves is called the solute while the substance that dissolves the solute is called the solvent.
-In a solution of a carbonated beverage, water acts as the solvent which dissolves the components added as solute to make the beverage. These components include sugars and other types of salts such as sodium citrate, all dissolved in water.

Answer:
- <u><em>Sodium fluoride</em></u>
Explanation:
A <em>solution </em>is constituted by two parts: the solute and the solvent (there may be more than 1 solute and more than 1 solvent, but that is not the key of the answer).
<em>Solute</em> is the substace that is dissolved and it is in less amount than the solvent.
<em>Solvent</em> is the substance that can dissolve the solute and it is a greater amount than the solute.
In the given solution:
- <em>sodium fluoride</em>, <em>85.0 mL</em>, is the solute,
- <em>water</em>, <em>350.0 mL</em> is the solvent, and
- the mixture of both substances is the solution.
