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

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 the pH of strong acids?

Back

Strong acids have a pH closer to 0.

Front

What is the pH of strong bases?

Back

Strong bases have a pH closer to 14.

Front

What are common properties of acids?

Back

Acids typically have a sour taste, can react with metals, and have a pH below 7.

Front

What are common properties of bases?

Back

Bases typically have a bitter taste, feel slippery, and have a pH above 7.

Front

What is the role of H+ ions in acids?

Back

H+ ions are responsible for the acidic properties of a solution.

Front

What is the role of OH- ions in bases?

Back

OH- ions are responsible for the basic properties of a solution.

Front

What happens when an acid reacts with a base?

Back

When an acid reacts with a base, they neutralize each other, forming water and a salt.
