This study used a descriptive approach. Data collection techniques using data triangulation technique from the results of the Three-Tier Diagnostic Test (TTDT), formative tests, and interviews. The sample used in this study was determined using a purposive sampling technique. Based on the research conducted, high school students in Surakarta experienced misconceptions in salt hydrolysis material as much as 36.75%, 35.94% Scientific knowledge, 15.63% lack of knowledge, and 10.90% error. Most misconceptions experienced by high school students in Surakarta on salt hydrolysis material occur in sub concepts: a) conclude the acid-base properties shown from salt solutions (49.91%), b) calculate the pH of the salt solution (39.15), c) analyze the reaction salt hydrolysis (37.21%), d) analyze the concept of hydrolysis that occurs in solution (35.98), e) determine the types of hydrolysis of salt (21.87%).
