We have a base called potassium hydroxide, reacting with an acid called hydrochloric acid. When equal amounts of a strong acid such as hydrochloric acid are mixed with a strong base such as sodium hydroxide, the result is a neutral solution. to give one molecule of calcium sulfate and TWO molecules of Calcium sulfate is a. Lets write the molecular, total ionic, and net ionic equations for an ACID BASE neutralization reaction. Doing that is left to the reader. Problem #34: Write the net ionic equation for this reaction: The net ionic would not eliminate anything, however there would be one change from the molecular equation above: The one change is because calcium acetate is a strong electrolyte and, as such, should always be written as ions when in solution. For example: Problem #40: What is the net ionic equation for dissolving solid glucose? It simply became part of the aqueous solution. Since you're not sure about cobalt(II) sulfate, you look it up and find it to be soluble. D. Weak Acid + Weak Base Split soluble compounds into ions (the complete ionic equation).4. 2.
