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.
