Lets write the molecular, total ionic, and net ionic equations for an ACID BASE neutralization reaction. Problem #46: Write the net-ionic equation for this reaction: 2) Remove the spectator ions (sodium ion and nitrate ion): 3) But wait, there's more! Hence, it is written in ionic form, i.e. Because they are positively charged, all metal ions are cations. This is called a neutralization reaction. Yup, it's NR. Ca(OH)2 (s) + 2HCl (aq) = CaCl2 (aq)+ 2H2O (l) For example: Problem #40: What is the net ionic equation for dissolving solid glucose? Michael McClure M.S., Emeritus Professor, Chemistry. So, acid + base ---> salt + water that occurs when ammonium Write the state (s, l, g, aq) for each substance.3. Since you're not sure about cobalt(II) sulfate, you look it up and find it to be soluble. EXAMPLE 1 - Predicting Precipitation Reactions: Predict whether a precipitate will form when water solutions of silver nitrate, AgNO 3 (aq), and sodium sulfide, Na 2 S(aq), are mixed. To write the net ionic equation for Na2CO3 + HCl we follow three steps. Since the solid state is considered to NOT be dissociated, it is written as the full formula. 2) The question now becomes: Are either of the two products insoluble in aqueous solution? Finally, we cross out any spectator ions. Hence, it is written in molecular form. The balanced equation will be: When an acid and a base react with each other, the products that are formed is a salt (an ionic compound that is formed from a reaction between an acid and a base) and water.
