An acid is a chemical substance that donates hydrogen ions.
Give an example of a strong acid.
Hydrochloric acid (HCl)
What is a base?
A base is a chemical substance that accepts hydrogen ions.
Provide an example of a strong base.
Sodium hydroxide (NaOH)
What are the properties of acids?
Acids taste sour, turn blue litmus paper red, and have a pH less than 7.
What are the properties of bases?
Bases taste bitter, turn red litmus paper blue, and have a pH greater than 7.
What is a salt?
A salt is a compound formed when acids and bases react, resulting in the replacement of hydrogen ions of the acid with positive ions from the base.
Give an example of a common salt.
Sodium chloride (NaCl)
What is the pH scale?
The pH scale is a measure of the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral, values less than 7 being acidic, and values greater than 7 being basic.
What is the pH of water?
The pH of water is 7, making it neutral.
What is an indicator?
An indicator is a substance that changes color depending on the pH of the solution it is in.
Name a commonly used indicator.

What is neutralization?
Neutralization is a chemical reaction between an acid and a base, resulting in the formation of a salt and water.
