Molecular equation: H 2 SO 4 (aq) + Ba (OH) 2 (aq) ---> BaSO 4 (s) + 2H 2 O (l) So the molecular form of the equation is shown above. A small percentage of the acid molecules do actually ionize (break apart into ions) when they dissolve in water, but most of the weak acid molecules do not ionize. The OH and H+ will form water. Write the dissolution equation for any given formula of a water-soluble ionic compound. For ionic equations like these it's possible for us to eliminate, essentially subtract out, spectator ions from an equation.

Remember to show the major species that exist in solution when you write your equation. Acetic acid, HC2H3O2, is a weak acid. To be more specific, they form a covalent molecule as opposed to a soluble ionic compound (if they made an insoluble ionic compound, they would not get cancelled out as spectator ions either). Instead of using sodium How can we tell if something is a strong base or acid? Direct link to Hema Punyamoorty's post At 0:50, it is said that , Posted 6 years ago. And while it's true And in solution, the ammonium cation acts as a weak acid and donates a proton to water to form the hydronium ion, With ammonia (the weak base) in excess here that means the solution's pH is going to be dominated by it more so compared to the other chemicals.
