WebProcedure. First, express the percent of solute as a decimal: 5% = 0.05. Multiply this decimal by the total volume: 0.05 x 1000ml = 50ml (ethylene glycol needed). Subtract the volume of solute (ethylene glycol) from the total solution volume: 1000ml (total solution volume) - 50ml (ethylene glycol volume) = 950ml (water needed) WebWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +.
