Acid-base is one of the first abstract chemistry course that high school student encounter. Research shows that many students find difficulty on the definition, macroscopic and microscopic conceptual comprehend. This research has the aim to identify the student’s conceptual understanding in acid-base course. The subject for this research is 145 students from government school 2018/2019 school year. The data collected through 16 questions of the three-tier diagnostic test and questionnaire. Three validators validate the question with an average score of 159 from 176. The average score for the questionnaire is 39.75 with good category, and the Alpha Cronbach reliability is 0.714. Analysis of the result shows that the student has several difficulties with acid-base conceptual. Classical result for 145 students are 28% of the student understands the concept, 4% lack of conceptual understanding, 43% misconception and 21% don’t understand the concept of acid-base.
