The purpose of this study was to investigate the teaching through problem based learning in chemical equilibrium for Standard XI. Chemical equilibrium is fundamental to the understanding of acid- base behaviour, oxidation-reduction reactions and solubility. The complete composition of Chemicals and all the compositions in compound reactions and mixtures at equilibrium are discussed in detail. Problem solving strategy considered for Chemical equilibrium contents taught easily with deep understanding in a short period, enabling one to understand it while ensuring important elements are taking into account. In the Constructivism, Problem solving means students had to share their knowledge, express their ideas and experience with each other while searching a solution to the problem and work together in small groups toward a common problem. Problem solving is an educational approach to teaching and learning that involves groups of learners working together to solve a problem, complete a task and create a Conclusion. Problem solving activities are vary widely, but most center on students' exploration or application of the course material, not simply the teacher's presentation or explication of it. Chemical equilibrium concepts achievement test was administered to all students of experimental group and control group, and result was significant.
