These worksheets work on understanding the properties of acids and bases in a chemistry based environment.

By the time we are ready for school, we have all heard the about acids and how bad they are. Many acids are very helpful to use in everyday life. When looking at acids and bases we are completely worried about the change or transfer of hydrogen or hydroxide ions. If a particular substance has many hydrogen ions, it is an acid. If it has a bunch of hydroxide ions, it’s a base. We use a pH scale to classify substance that ranges from 0 to 14, with 7 being neutral (meaning neither an acid nor a base. The closer a substance is to 0, the more of an acid it is. The closer to 14 a substance is, the more it is a base.

The worksheets work on identifying acids and bases based on a number of different criteria and your understanding of ion transfer.

Are They Acids, Bases, or Salts?

Classify each of the following substances as an acid, a base or a salt.

Understanding the pH Scale

Identify whether the solutions listed below are acids or bases. Write the color expected for each indicator (phenolphthalein, litmus dye) when immersed and indicate the pH range you would expect.

Classify the Compounds

Determine the nature of each compound and determine if it would be weak or strong.

Understanding the pH Scale

Work on figuring out how each pH level would react with Blue Litmus, Phenolphthalein, and Red Litmus.

pH of Salt Solutions

The strong bases are the Group I and Group II hydroxides and most others are considered weak. Provide the missing chemical formulas and terms in the chart below.

Conductors and Electrolytes

Which substance would allow current to travel in the presence of water?
