The purpose of this research was to observe the influence of practical guide based on the inquiry approach toward student achievement on the subject of pH scale and the use of indicators. The research was carried out in the chemistry education study program, Medan State University. Before the hypothesis measure test, the normality and homogeneity test was performed first, signed both of distributed samples has normal and homogeneous. The results of the research shown that there was the influence of practical guide based on the inquiry approach toward student achievement on the subject of the pH scale and the use of indicators, the average of the learning result and percentage gain which taught by practical guide based on inquiry approach are 78.74 and 66.9 respectively while the results of learning chemistry and percentage gain taught with conventional practical guide are 73.03 and 59.4, with difference of percentage gain equal to 7.4. The hypothesis in this study was tested by using the right-t-test and hypothesis testing results obtained t count higher than t table with the value, 3.167 is higher than 1.669 with alpha is 0.05.
