This research is a quantitative descriptive study that aims to analyze the increase in activity and learning outcomes of salt hydrolysis of Class XI MIPA students at SMA Negeri 11 Makassar through discovery learning model. The types of activities that are used as indicators are visual, writing, oral, listening and mental activity. Learning outcomes are seen from five indicators, namely: 1) Understanding the principle of the hydrolysis reaction, 2) Analyzing salts that undergo hydrolysis, 3) Writing the hydrolysis reaction equation, 4) Determining the hydrolysis constants and pH of the hydrolyzed salt solution, and 5) Determining the graph the relationship between changes in pH value in acid-base titrations to explain the nature of the hydrolyzed salt. Research data obtained through observation of learning activities during learning process and evaluation at the end of each lesson of salt hydrolysis. The results shows that students' learning activities other than oral and listening activity are in the very active category in all syntax, but for oral and listening activities in data processing syntax and proof that initially in the active enough category, each meeting has increased into a category active at the next meeting. Likewise, learning outcomes have increased from each meeting by 14%. The indicators of salt hydrolysis that experience completeness are the first, the fourth and the fifth indicators. © 2021 Published under licence by IOP Publishing Ltd.
