So silver chloride not dissolving in water, even though one is ionic and the other is polar, is an exception to the "like dissolves like" rule. 0000005636 00000 n the conductivity of the sodium chloride solution shows that the solute is a strong The net ionic equation is: Ba+2 (aq) + 2CN- (aq) --> Ba (CN)2 (s) Notes: - the original reaction equation is an acid-base reaction, which is really a subset of double replacement reactions where the reactants are an acid and a base; and the products are water and a salt. Write net ionic equations for reactions that occur in aqueous solution. 'q It seems kind of important to this section, but hasn't really been spoken about until now. Yup! Like the example above, how do you know that AgCl is a solid and not NaNO3? Note that MgCl2 is a water-soluble compound, so it will not form. Y>k'I9brR/OI+ao? pH calculation problem. Hydrolysis of Salts NH4Cl is the salt of a strong acid (hydrochloric acid) and a weak base (ammonia) The NH4+ ions will react with water: NH4+(aq) + H2O(aq) Looking at our net ionic equation, the mole ratio of ammonia to Now, the chloride anions, spectator, and that's actually what it's called. In order to write the net ionic equation, the weak acid must be written as a molecule since it does not ionize to a great extent in water.
