Acids Bases and Salts

Front

What is an acid?

Back

An acid is a substance that increases the number of hydrogen ions (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A base is a substance that increases the number of hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is the pH scale?

Back

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

Front

What is a neutral solution?

Back

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

Front

What is an indicator?

Back

An indicator is a substance that changes color in the presence of an acid or a base, helping to determine the pH of a solution.

Front

What is the pH range of acids?

Back

The pH range of acids is less than 7.

Front

What is the pH range of bases?

Back

The pH range of bases is greater than 7.

Front

What is a salt?

Back

A salt is a compound formed when an acid reacts with a base, typically consisting of a positive ion from the base and a negative ion from the acid.

Front

What is a strong acid?

Back

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

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, releasing some but not all of its hydrogen ions.
