The research subjects were 44 students from one of the State High Schools in Cimahi who had studied salt hydrolysis material. The research method used is descriptive method using two-level multiple-choice metal model diagnostic test instruments. Based on the research, it was found that the concept of salt that can produce acidic solutions was dominated by 32% of students who already understood the concept of salt which can produce acidic solutions based on their properties, measurement of pH of the solution and the effect of comparison of Kb and Ka through macroscopic to submicroscopic and symbolic levels. In the concept of salt that can produce alkaline solutions, it is dominated by 36% of students who already understand the concept of salt that can produce alkaline solutions based on their nature, measuring the pH of the solution and the effect of the comparison of Kband Ka through the macroscopic level to the submicroscopic and symbolic. While the concept of salt that can produce neutral solutions is dominated by 52% of students who still experience misconceptions on the concept of salt that can produce a neutral solution based on its nature and measurement of pH of the solution, students already understand that if the salt is dissolved in water will produce a neutral solution but cannot explain at the submicroscopic level about reactions that occur in salts that can produce neutral solutions.
