Concept explainers

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Suppose a group of students put 2.92 grams of an unknown solid acid into a 250-mL volumetric flask and filled it up to the mark with deionized water. After this they pipetted out 15.75 mL of a 1.78 M NaOH(aq) solution into another 250-mL volumetric flask and filled it up to the mark with deionized water. The students were given a pH meter that was already calibrated by their teaching assistant (T.A.) and they got the following result shown in the table below. Calculate the Molarity of the unknown solid acid. Hint: You can approximate the endpoint of the titration by taking the average volume between two consecutive titrant volume reading and you can assume that it is a 1:1 stoichiometry ratio between the acid and OH-(aq).
