WebBy counting the number of atoms of each element, we find that only one water molecule is formed as a product. However, in the reaction between HCl (aq) and Mg (OH) 2 (aq), additional molecules of HCl and H 2 O are required to balance the chemical equation: 2HCl (aq) + Mg (OH) 2 (aq) → 2H 2 O (ℓ) + MgCl 2 (aq) Here, the salt is MgCl 2. WebJul 24, 2016 · Explanation: Barium hydroxide is a strong base for both stages of dissociation: Ba(OH)2(s) → Ba2+ +2OH− So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: [H+][OH−] = 1.0 ×10−14M [OH−] = 2.0 × 10−1M [H+] = 5.0 ×10−14M And then pH = −log10([H+] = 5.0 × 10−14) = 13.30.
