WebQuestion: In an electrolysis experiment, a class measured the amount of copper precipitated from a saturated solution of copper sulfate over a 30-minute period. The n = 35 students calculated a sample mean and standard deviation equal to 0.128 and 0 mole respectively. What is the upper bound of the 90% confidence interval when estimating … WebAug 15, 2024 · For any electrolysis the electrical charge Q passing through an electrode is related to the amount of electrons n e – by \[F=\dfrac{Q}{n_{e^-}}\] Thus F serves as a conversion factor between … how strong are minks in one piece

Web63.55 g (copper ions) + 2 faradays ---> 63.55 g (copper atoms) From this equation we see that 63.55 grams of copper “plate out” onto the cathode for every two faradays of electric charge. Of course, the same amount of copper would oxidize from the anode. SAFETY REMINDERS. Wear protective gear. Follow directions for using the equipment. mersey smart card
