Acids and Bases Test

Front

What is the pH scale?

Back

The pH scale is a measure of how acidic or basic a solution is, ranging from 0 to 14.

Front

What does a pH of 7 indicate?

Back

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

Front

What is an acid?

Back

An acid is a substance that donates hydrogen ions (H+) in a solution, typically having a pH less than 7.

Front

What is a base?

Back

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

Front

What is a strong acid?

Back

A strong acid is an acid that completely dissociates in water, resulting in a low pH (usually below 3).

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, resulting in a higher pH than strong acids (usually between 3 and 6).

Front

What is a strong base?

Back

A strong base is a base that completely dissociates in water, resulting in a high pH (usually above 11).

Front

What is a weak base?

Back

A weak base is a base that partially dissociates in water, resulting in a lower pH than strong bases (usually between 8 and 10).

Front

What is the significance of the number 14 on the pH scale?

Back

A pH of 14 indicates a very strong base.

Front

What is the significance of the number 0 on the pH scale?

Back

A pH of 0 indicates a very strong acid.
