pH (Acids/Bases)

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.

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, meaning it is neither acidic nor basic.

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in water, releasing all of its protons.

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, meaning not all of its protons are released.

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in water, releasing all of its hydroxide ions.

Front

What is a weak base?

Back

A weak base is a base that partially dissociates in water, meaning not all of its hydroxide ions are released.
