b. What is the range of the values on the horizontal axis?

c. What is the solubility of carbon dioxide at ${25}^{\circ }C$ ?

d. At what temperature does carbon dioxide have a solubility of $0.20 g/100 g$ water?

Step-by-Step Solution

Answer

a. On the horizontal axis, the value of temperature is measured.

b.  The range of values on the horizontal axis is $0-{10}^{\circ }C$.

c. The solubility of carbon dioxide at ${25}^{\circ }C$ is $0.15 g/100 g$ water.

d.  At ${15}^{\circ }C to {16}^{\circ }C$, carbon dioxide have a solubility of $0.20 g/100 g$ water.

Step 1: Part (a) Given Information

The graph between the solubility of Carbon dioxide in water v/s temperature is given below:

Step 2: Part (a) Explanation

The amount of a substance that dissolves in a certain quantity of water (e.g.$100 g$) at a particular temperature is referred to as solubility in water. As the temperature of the water varies from $0^{\circ }C - {100}^{\circ }C$ , the mass of solute that dissolves in of water changes. The graphical representation of this relationship is known as the solute’s solubility curve.

In the graph, the vertical axis i.e., the y-axis represents the solubility of carbon dioxide in the water while the horizontal axis i.e., the x-axis shows the values of temperature.

Step 1: Part (b) Given Information

On the horizontal axis, the temperature range is given.

Step 2: Part (b) Explanation

In the graph, the vertical axis i.e., the y-axis represents the solubility of carbon dioxide in the water while the horizontal axis i.e., the x-axis shows the values of temperature.

The range of temperature varies from $0^{\circ }C$ to  ${10}^{o}C$.

Step 1: Part (c) Given information

The solubility of carbon dioxide at ${25}^{\circ }C$.

Step 2: Part (c) Explanation

As per the solubility curve, the solubility of carbon dioxide in  water at ${25}^{\circ }C$is  $0.15 g$ per  $100 g$ water.

Referring to the graph, each point on the solubility curve represents a saturated solution while an unsaturated solution can be represented as any point on a graph below a solubility curve.

The graph is shown as follows:

Step 1: Part (d) Given information

The temperature for solubility of carbon dioxide $0.20 g/100 g$ water needs to be mentioned.

Step 2: Part (d) Explanation

As per the solubility curve, the solubility of  $0.20 g$ carbon dioxide in $100 g$ water is between ${17}^{\circ }C to {18}^{\circ }C$.

Referring to the graph, each point on the solubility curve represents a saturated solution while an unsaturated solution can be represented as any point on a graph below a solubility curve.

The graph is shown as follows:

the solubility curve, the solubility of  $0.20 g$ carbon dioxide in $100 g$ water 18 deg celsius.
