Ionic equations and state symbols

• What do ionic equations show?

  Ionic equations show the ions formed in solution and which particles are reacting.
• What types of substances typically form ions in solution?

  Acids, bases, and salts form ions in solution.
• What is the standard balanced equation for an acid reacting with a base?

  The standard balanced equation is $H_2SO_4 +$$2KOH \rightarrow K_2SO_4 +$$2H_2O$.
• What is the full ionic equation for the reaction of sulfuric acid and potassium hydroxide?

  The full ionic equation is $2H^+$$+$$SO_4^{2-} +$$2K^+$$+$$2OH^- \rightarrow 2K^+$$+$$SO_4^{2-} +$$2H_2O$.
• What are spectator ions in an ionic equation?

  Spectator ions are ions that do not participate in the reaction.
• What must balance in the final ionic equation?

  The charges must balance on the left and right sides of the equation.
• What are the state symbols used in chemical equations?

  State symbols are (s) for solids, (l) for liquids, (g) for gases, and (aq) for aqueous solutions.
