Web3. +Calculate the pH of 5.0 x 10-8 M HClO 4. What fraction of total H in this solution is derived from dissociation of water? Because the concentration of HClO 4, a strong acid, is so low, it appears that water can be a significant source of H+ and we should use the systematic approach to solving this problem. Step 1) Reactions: 1) HClO. 4-→ ... WebBase Dissociation Constants at 25°C. Although all compounds have a characteristic solubility in water at a given temperature, some families of compounds are more soluble than others and it is useful to know certain general rules of solubility. We call any substance insoluble its solubility is less than 0.01 mol/L.
