A volume of 10 mL of an unknown hydrochloric acid sample was diluted to 100 mL. The diluted solution was then titrated against a solution of sodium carbonate (prepared by dissolving 0.2188 g of solid in 50 mL distilled water). Hydrochloric acid reacted with sodium carbonate according to the following equation: 2 HCI (aq) + Na,CO3 (aq)H20 () + CO2 (g) + 2 NaCl (aq) A volume of 15.2 mL of the hydrochloric acid was required to complete the reaction in the titration process. A second titration was done between the same acid sample against a blank for indicator correction, a volume of 0.3 mL was consumed by the indicator.
