Learners investigated the relationship between the concentration of a silver nitrate (AgNO3) solution and its conductivity at a constant temperature. They set up the apparatus, as shown below, and recorded the current. The initial reading of the ammeter was taken before anhydrous AgNO3 was added to distilled water. The anhydrous AgNO3 was added to 200 … Read more
