For this purpose, a two-tier diagnostic test consisting of 44 items (α = 0.84) related to the aforementioned concepts was developed by the researchers. This test was applied on to the first, second, and third year pre-service science teachers in Hasan Ali Yucel Education Faculty, Istanbul University. The results showed that the pre-service science teachers had alternative conceptions about endothermic-exothermic reactions, conservation of energy, reaction enthalpy, calorimeters; rate of reaction, reaction rate constant, effects of some factors on reaction rate and reaction rate constant; effects of some factors on equilibrium, equilibrium dynamics, Le Chatelier Principle; equivalence point, end point, indicators, buffers, titrations, neutralization, strength and properties of acids and bases, pH; effects of concentrations on cell potential, metal electrodes, localization of anode and cathode, plating, galvanization.}, keywords = {acids and bases, Alternative Conception, chemical equilibrium, chemical kinetic, electrochemistry, thermochemistry, two tier diagnostic test}, issn = {1648-3898}, doi = {https://doi.org/10.33225/jbse/16.15.79}, url = {http://oaji.net/articles/2016/987-1481286347.pdf}, author = {Ayfer Mutlu and Bur{\c c}in Acar {\c S}e{\c s}en} }
