The original theory of acids and bases was proposed by Svante August Arrhenius around 1884. An Arrhenius is any substance that increases the number of hydrogen ions (H+) in an aqueous solution. An Arrhenius base is any substance that increases the number of in an aqueous solution.
What will hydrochloric acid form when added to water?

Gilbert Lewis proposed a different mechanism for acid-base theory, also around 1923. The Lewis theory is based on the
The common acids are all formed from a negative ion and a negative hydroxide ion.
What is a precipitation reaction?
A precipitation reaction can sometimes occur when two are mixed together in an aqueous solution.
These are guidelines that help you to identify insoluble compounds known as
Use the solubility rules and the dropdown menus to indicate whether each compound is aqueous or solid.
Rb2S() + CuI2() -> 2RbI() + CuS()
This is the ionic equation for question 16.
2Rb+1(aq) + S-2(aq) + Cu+2(aq) + 2I-1(aq) -> 2Rb+1(aq) + 2I-1 (aq) + CuS(s)
Fill in the dropdown menus with the correct net ionic equation by removing the spectator ions.
