Solubility Curves and Concentrations

Front

What is a solubility curve?

Back

A graphical representation showing the amount of solute that can dissolve in a solvent at various temperatures.

Front

What does it mean for a solution to be saturated?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature.

Front

Define a supersaturated solution.

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature, often achieved by heating.

Front

How do you calculate percent by volume concentration?

Back

Percent by volume = (Volume of solute / Total volume of solution) x 100.

Front

What is molarity (M)?

Back

Molarity is a measure of concentration defined as moles of solute per liter of solution.

Front

How do you calculate the number of grams needed for a specific molarity?

Back

Grams needed = Molarity (M) x Volume (L) x Molar mass (g/mol).

Front

What is the molar mass of potassium carbonate (K2CO3)?

Back

The molar mass of K2CO3 is approximately 138.21 g/mol.

Front

What is the effect of temperature on solubility?

Back

Generally, solubility of solids increases with temperature, while the solubility of gases decreases.

Front

What is the relationship between concentration and taste in solutions?

Back

Higher concentrations of solute typically result in a sweeter taste in solutions.
