EXTRA CREDIT: +4 pоints pоssible A titrаtiоn is performed using sodium hydroxide, NаOH, аt a concentration of 0.1211 M to determine the concentration of a hydrochloric acid solution of unknown concentration. A volume of 10.00 mL of the hydrochloric acid solution is used in each trial. Using the balance chemical reaction and data table below, determine the concentration of the hydrochloric acid solution. HCl(aq) + NaOH(aq) --> NaCl(aq) + H2O(l) Concentration of NaOH 0.1211 M Volume of HCl used 10.00 mL Initial buret reading of NaOH 0.35 mL Final buret reading of NaOH 14.20 mL
