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

Front

What are some common properties of acids?

Back

Acids taste sour, conduct electricity when dissolved in water, and react with metals to produce hydrogen gas.

Front

What are some common properties of bases?

Back

Bases taste bitter, feel slippery, and can conduct electricity when dissolved in water.

Front

What is an example of a strong acid?

Back

Hydrochloric acid (HCl) is an example of a strong acid.

Front

What is an example of a strong base?

Back

Sodium hydroxide (NaOH) is an example of a strong base.

Front

What is the significance of pH 7?

Back

pH 7 is significant because it indicates a neutral solution, where the concentration of hydrogen ions equals the concentration of hydroxide ions.
