Next, lets write the Total Ionic Equation, like this. Explanation: The reaction between Hydrochloric Acid (HCl) and Lithium Hydroxide (LiOH) is a Neutralization reaction. Ca(OH)2 is only slightly soluble, but what does dissolve, ionizes 100%. The hydrogen in the HCl is transfered (as an ion) to the water, making H3O+, which is called the hydronium ion. CaH (s)+HOH (g)+Ca (aq)+OH (aq) excess silver acetate is added to a solution of trisodium phosphate. Weak Acid + Strong Base However, the above equation is not correct, since it is not balanced. To write the net ionic equation, well cancel out ALL spectator ions. Let's start by writing a complete molecular equation: 3) Eliminate spectator ions to get the net ionic: However, nothing tells you to eliminate sodium ion until you actually do the problem. Explanation: There is no need to include water in the ionization equation, you just need to include the states in your equation: Ca(OH)2(s) Ca2+(aq) +OH (aq) You may want to write an equation corresponding to the hydroxide displacement in water (The Grotthuss mechanism) but it is not a measurable process since the reactants and products are the same.
