The experiment determined the composition of a mixture through acid-base titration using phenolphthalein and methyl orange indicators. The average volume of HCl used with phenolphthalein was 10.24 mL, indicating the presence of hydroxide ions. The average volume used with methyl orange was 15.34 mL, with the difference of 5.1 mL indicating the presence of carbonate ions. Therefore, the mixture contained both sodium hydroxide and sodium carbonate.
