This is the 4th part to the lab where we are changing the cupric oxide to Cupric chloride. This picture shows the 8 ml of HCl poured into the cupric oxide therefore changing the color from black to green. We are forming Cupric Chloride. We strive for accuracy by making sure that all of the copper is washed out of the funnel with water. We wanted to make sure that no copper was lost.
