What is a saturated solution?

Back

A saturated solution is one that has dissolved the maximum amount of solute at a given temperature and pressure, meaning no more solute can dissolve in the solvent.

Front

What are solutions made up of?

Back

Solutions are made up of solutes (the substance being dissolved) and solvents (the substance doing the dissolving).

How many grams of K2Cr2O7 are soluble in 100 g of water at 95 ºC?

Back

75 grams of K2Cr2O7 are soluble in 100 g of water at 95 ºC.

Front

What pH value indicates a basic solution?

Back

A pH value greater than 7 indicates a basic solution.

Front

What is the pH range of human blood?

Back

The pH of human blood ranges between 7.35 and 7.45, making it slightly basic.

Front

Define solute.

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

Define solvent.

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What is the difference between a concentrated and a dilute solution?

Back

A concentrated solution has a large amount of solute relative to the amount of solvent, while a dilute solution has a small amount of solute relative to the solvent.

Front

What is a supersaturated solution?

Back

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

Front

What does it mean if a solution is unsaturated?

Back

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