Back

An electrolyte is a substance that, when dissolved in water, produces ions and can conduct electricity.

Front

What is the difference between a strong acid and a weak acid?

Front

What is the pH scale?

Back

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

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 a substance that dissolves a solute, forming a solution; water is the most common solvent.

Front

What is the role of water in acid-base reactions?

Back

Water can act as both an acid and a base, depending on the substances it interacts with.

Front

What is the definition of a strong base?

Back

A strong base is a substance that completely dissociates in water to produce hydroxide ions (OH-).
