Acids & 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+) in a solution and has a pH greater than 7.

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a substance is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is a neutral substance?

Back

A neutral substance has a pH of 7, meaning it is neither acidic nor basic. An example is pure water.

Front

What is a characteristic of acids?

Back

Acids typically have a sour taste and can be corrosive.

Front

What is a characteristic of bases?

Back

Bases often feel slippery and can taste bitter.

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 happens when an acid and a base react?

Back

They undergo a neutralization reaction, producing water and a salt.

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.
