Therefore, the purpose of this study is to produce teaching materials in the form of REACT-based acid-base Student Worksheets (LKPD) for class XI Senior High School which are valid and practical and to determine the level of validity and practicality of the REACT-based acid-base worksheets that have been developed. The method used in the development or Research and Development (R&D).
