<![CDATA[This research aimed at developing a buffer solution textbook based chemical representation; describe the characteristics of a buffer solution textbook based chemical representation; describe the teachers’ feedback and students’ response to a buffer solution textbook based chemical representation; and knowing the obstacles encountered when developing a buffer solution textbook based chemical representation. The research method used is the Research and Development. From the results of limited test data showed that compliance with the chemical content of the textbook curriculum is very high at 82,5%, the aspect graph/the attractiveness is very high at 95% and levels of legibility is very high at 89,55%. Penelitian ini bertujuan untuk mengembangkan buku ajar larutan penyangga berbasis representasi kimia; mendeskripsikan karakteristik buku ajar larutan penyangga berbasis representasi kimia; mendeskripsikan tanggapan guru dan siswa terhadap buku ajar larutan penyangga berbasis representasi kimia; dan mengetahui kendala-kendala yang dihadapi ketika mengembangkan buku ajar larutan penyangga berbasis representasi kimia. Metode penelitian yang digunakan adalah metode Penelitian dan Pengembangan.
