This study aims to develop a textbook containing Higher Order Thinking Skills (HOTS), especially on the colligative properties of solutions. The development model in this study adopts the 4D model (Define, Design, Development, and Disseminate). Product assessment was carried out by material experts, media experts, chemistry teachers, and student responses. The research instruments were validation sheets, product quality assessments, and student response sheets. The product is in the form of a textbook containing Higher Order Thinking Skill (HOTS) on colligative properties consisting of 9 sub-chapters of material and printed in B5 size. The results showed that the results of product assessment by media experts obtained an ideal percentage of 92% with an excellent category; material experts got 94% ideal percentage with the excellent category; chemistry teachers obtained an ideal percentage of 89.4% with an excellent one category. The book containing the Higher Order Thinking Skill (HOTS) colligative properties of this solution also received a positive response with a percentage of 98%. Therefore, the textbook is suitable for improving students' higher-order thinking.
