Acids and Bases

Front

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 produces hydroxide ions (OH-) in a solution and has a pH greater than 7.

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 is a characteristic property of acids?

Back

Acids typically have a sour taste and can react with metals to produce hydrogen gas.

Front

What is a characteristic property of bases?

Back

Bases typically have a bitter taste, feel slippery, and can produce hydroxide ions (OH-) in solution.

Front

What happens when an acid reacts with a base?

Back

When an acid reacts with a base, they undergo a neutralization reaction, producing water and a salt.

Front

What is an example of a common acid?

Back

Common examples of acids include hydrochloric acid (HCl) and citric acid (found in citrus fruits).

Front

What is an example of a common base?

Back

Common examples of bases include sodium hydroxide (NaOH) and baking soda (sodium bicarbonate).

Front

What is the strongest acid on the pH scale?

Back

The strongest acids have pH values close to 0.

Front

What is the strongest base on the pH scale?

Back

The strongest bases have pH values close to 14.
