Front

What are weak acids?

Back

Weak acids are acids that do not completely dissociate in solution. Examples include vinegar and fruit juice.

Why is it dangerous to taste unknown acids and bases?

Back

Unknown acids and bases may be dangerous and can cause harm if ingested.

Front

What is the pH range of acids?

Back

Acids have a pH below 7.

Front

What is the taste characteristic of bases?

Back

Bases typically have a bitter taste.

Front

What is the definition of 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 the definition of a base?

Back

A base is a substance that accepts protons (H+) in a solution and has a pH greater than 7.

Front

What is the role of indicators in acid-base chemistry?

Back

Indicators are substances that change color in response to the pH of a solution, helping to identify whether it is acidic or basic.

Front

What is the neutral pH value?

Back

The neutral pH value is 7, which indicates a balanced concentration of hydrogen ions and hydroxide ions.

Front

What happens when an acid reacts with a base?

Back

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