This research aimed to find out the profile of misconception in senior high school students on the concept of acid-base strength and its factors causing. The research design used was qualitative descriptive. The data collection was carried out by two-tier pictorial multiple-choice diagnostic tests on the concept of acid-base strength modified by the previous researcher from, which consist of seven items and had been valid and reliable. In addition, the data were collected by using a questionnaire, interviews with students who's having misconceptions and the chemistry teachers who taught the students, and documentation of a chemistry textbook. The findings showed that: (1) students having misconceptions on the concept of acid-base strength; (2) the biggest misconception was the target concept of the relationship between acid strength and pH with a percentage of 51.52%; (3) student misconception was caused by various factors, namely the condition of students, experiences, teachers, and textbooks.
