"December, 1976." Vita. Thesis (M.A.T. Chemistry)--University of the Philippines, Diliman. The purpose of the study was to investigate the reactivity of metals with hydrochloric acid, with the aim of devising a laboratory activity on reaction rates adapted to a secondary chemistry course. The researcher found out that the experiments are economical and can easily be duplicated in as much as the materials used are readily available in a typical barangay school. The experimental results were found to be reliable, consistent and reproducible within certain limits. Reaction mechanisms (Chemistry). Hydrochloric acid.
