SUMMARY
The discussion centers on determining the identity of an unknown acid (hydrochloric, sulfuric, or phosphoric) with a concentration of 0.2128 M, using a titration method with 0.2723 M sodium hydroxide. A total of 32.83 mL of sodium hydroxide was required to titrate 21.00 mL of the unknown acid. The key to solving the problem lies in calculating the moles of H+ ions present, which must be an integer multiple of the acid's concentration. This approach allows for the identification of the acid based on the stoichiometry of the reaction.
