Acid 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 donates 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 happens when an acid and a base react?

Back

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

Front

What is a neutral solution?

Back

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

Front

What is the pH of pure water?

Back

The pH of pure water is 7, indicating it is neutral.

Front

What is a strong acid?

Back

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

Front

What is a weak acid?

Back

A weak acid is an acid that partially dissociates in water, meaning not all of its protons are released.

Front

What is the effect of adding a base to an acidic solution?

Back

Adding a base to an acidic solution will increase the pH, making the solution less acidic.

Front

What is the pH of a solution with a high concentration of hydroxide ions (OH-)?

Back

A solution with a high concentration of hydroxide ions will have a pH greater than 7, indicating it is basic.
