Question

Analyze the graph to describe the solubility of barium nitrate, BaNO3.

At 60°C,________ (100g, 200g, 350g) must be added to 1 L of water to make a saturated solution.
At 25°C, the solubility is about ______ .(100 per L, 125 per L, 150 per L)
A solution that contains 600 g BaNO3 in
3 L of H2O at 70°C is ________. (saturated, supersaturated, unsaturated)
For a solution that contains 300 g BaNO3 in 3 L of H2O at 60°C to become saturated, _________ (100,200,300)g solute must be added.

Answer 1

Answer: The answers are

1) 200g

2) 100g per liter

3) unsaturated

4) 300

Explanation:

Answer 2

At 60°C, 200g must be added to 1 L of water to make a saturated solution. [Observing the graph we can see that at 60, 200g must be added]

At 25°C, the solubility is about 100 per L. [Observing the given graph]

A solution that contains 600g BaNO3 in 3L of H20 at 70°C is saturated.[By knowing the definition of Saturated solution]

For a solution that contains 300 g BaNO3 in 3L of H20 at 60°C to become saturated, 300g soluted must be added.

What are saturated solutions and solubility?

• A saturated solution is a solution that contains the maximum amount of solute that can be dissolved under the condition at which the solution exists.
• Solubility is the ability to be dissolved, especially in water or solution.
