Q. 9.1 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify the solute and the solvent in each solution composed of the following:

a. $10.0 g$ of $NaCl$ and $100.0 g$ of$H_{2}O$

b. $50.0 mL$ of ethanol, $C_2{H}_{6}O$, and $10.0 mL$ of $H_{2}O$

c. $0.20 L$ of $O_2$ and $0.80 L$ of $N_2$

Step-by-Step Solution

Answer

(Part a) $10.0g$ of $NaCl$ is Solute and $100.0 g$ of $H_{2}O$ is Solvent.

(Part b) $50.0 mL$of $C_2{H}_{6}O$ Ethanol is a Solvent and $10.0 mL$ of $H_{2}O$ is a Solute.

(Part c) $0.20 L$of $O_2$ is the Solute in this solution and $0.80 L$ of $N_2$ is the Solvent.

Part (a) Step1: Introduction.

The solvent is indeed the substance which smart action this same physical state of the solution (solid, liquid or gas). 

The solute seems to be the substance soluble by the solvent.

(part a) Step2: Given Information .

$10.0 g$ of $NaCl$ and $100.0 g$ of $H_{2}O$

To find which is solute and solvent. 

(part a) Step3: Explanation.

The Solute is $NaCl$, the relatively small quantity.

The Solvent is $H_{2}O$, the greater quantity.

(part b ) Step4: Given Information .

$50.0 mL$ of Ethanol, $C_2{H}_{6}O$ and $10.0 mL$ of $H_{2}0$

To find the Solute and the solvent.

(part b) Step5: Explanation .

The Solvent is a huge quantity of ethanol $\left(C_2{H}_{6}O\right)$.

The Solute is $H_{2}O$, which has a smaller amount.

(part c) Step 6: Given Information .

$0.20 L$ of $O_2$ and $0.80 L$ of $N_2$

To know which Solvent and which is Solute.

(part c) Step7: Explanation .

The Solute is $O_2$ with the lowest quantity.

The Solvent is $N_2$ with the larger.
