Practice for Solutions

Front

What is percent mass in a solution?

Back

Percent mass is the mass of the solute divided by the total mass of the solution, multiplied by 100. It indicates how much of the solution's mass is made up of the solute.

Front

How do you calculate the percent mass of a solution?

Back

Percent mass = (mass of solute / total mass of solution) x 100.

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases as temperature increases.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature and pressure.

Front

What is the effect of temperature on the solubility of KNO₃?

Back

As temperature increases, the solubility of KNO₃ increases.

Front

What is the relationship between temperature and solubility for KCl?

Back

The solubility of KCl also generally increases with temperature, but not as significantly as KNO₃.

Front

What is the significance of a solubility curve?

Back

A solubility curve shows the relationship between the solubility of a substance and temperature, allowing for predictions about how much solute can dissolve at different temperatures.

Front

At what temperature is the solubility of NaClO₃ equal to that of KNO₃?

Back

The solubility of NaClO₃ is equal to that of KNO₃ at 77 °C.

Front

What is a concentrated solution?

Back

A concentrated solution has a large amount of solute relative to the amount of solvent.

Front

What is a dilute solution?

Back

A dilute solution has a small amount of solute relative to the amount of solvent.
