Acids and Bases Properties and naming 2025

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What characterizes an acid?

Back

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

Front

What characterizes a base?

Back

A base is a substance that accepts protons (H+) or produces hydroxide ions (OH-) in a solution, typically having a pH greater than 7.

Front

What happens to the pH when an acid is added to water?

Back

The pH decreases, indicating an increase in acidity.

Front

What happens to the pH when a base is added to water?

Back

The pH increases, indicating an increase in basicity.

Front

What is a neutral solution?

Back

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

Front

What is a strong acid?

Back

A strong acid completely dissociates in water, releasing all of its hydrogen ions (H+). Examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).

Front

What is a strong base?

Back

A strong base completely dissociates in water, releasing all of its hydroxide ions (OH-). Examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton (H+).
