师范院校化学专业研究型实验教学体验课OA

Research-oriented experimental teaching has emerged as a prominent focus in higher education's pedagogical studies. Silver nitrate,a notably costly reagent,poses a dual opportunity when recovered from silver-containing waste:it mitigates environmental pollution and reduces experimental costs. The experiment requires simple equipment,enabling students to apply their learned knowledge and skills effectively in resolving operational and procedural challenges. This study utilizes the recovery of silver nitrate from silver-containing waste liquid as the experimental project,where students independently devise their experimental strategies. Through the implementation of the scheme,they engage in a research-based learning process,thereby fostering their scientific research acumen.
