SPS6- Solutions, Solubility Curves & Acids/Bases

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (solvent).

Front

What is a solute?

Back

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

Front

What is a solvent?

Back

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

Front

What is pH?

Back

pH is a scale used to measure the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What does it mean if a solution is neutral?

Back

A neutral solution has an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-), resulting in a pH of 7.

Front

What is an acid?

Back

An acid is a substance that increases the concentration of hydrogen ions (H+) in a solution, typically having a pH less than 7.

Front

What is a base?

Back

A base is a substance that increases the concentration of hydroxide ions (OH-) in a solution, typically having a pH greater than 7.

Front

What happens when you add a solute to a solvent?

Back

When a solute is added to a solvent, it dissolves, creating a solution.

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 a supersaturated solution?

Back

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