Acids and Bases Review

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. Examples include vinegar and lemon juice.

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. Examples include soap and baking soda.

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 is a neutral solution?

Back

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

Front

What is a salt?

Back

A salt is a compound formed from the reaction of an acid and a base, typically consisting of a cation from the base and an anion from the acid.

Front

What is the strongest acid on the pH scale?

Back

The strongest acid on the pH scale is hydrochloric acid (HCl), which can have a pH close to 0.

Front

What is the strongest base on the pH scale?

Back

The strongest base on the pH scale is sodium hydroxide (NaOH), which can have a pH close to 14.

Front

What is the taste of acids?

Back

Acids typically have a sour taste, as seen in citrus fruits like lemons and limes.

Front

What is the feel of bases?

Back

Bases typically feel slippery or soapy to the touch, which is why they are often used in cleaning products.

Front

What is an indicator?

Back

An indicator is a substance that changes color in response to the pH of a solution, helping to determine whether it is acidic or basic.
