Acids, Bases and pH

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction and typically has a sour taste.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) and typically produces hydroxide ions (OH-) when dissolved in water.

Front

What is the pH scale?

Back

The pH scale measures 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 reacts with a base?

Back

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

Front

What is a neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that results in the formation of water and a salt.

Front

What is a salt in chemistry?

Back

A salt is an ionic compound formed from the neutralization reaction of an acid and a base.

Front

What is the role of hydroxide ions (OH-) in a base?

Back

Hydroxide ions (OH-) are responsible for the basic properties of a substance, making it capable of neutralizing acids.

Front

What is a proton donor?

Back

A proton donor is a substance that can donate protons (H+) in a chemical reaction, typically an acid.

Front

What is a proton acceptor?

Back

A proton acceptor is a substance that can accept protons (H+) in a chemical reaction, typically a base.

Front

What is the significance of pH 7?

Back

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