How much copper(II)sulfate should you use to make 100.ml of a 0.050M solution for this experiment? Read the lab manual (PDF Lab Guide) for the correct formula of the chemical you will be using since the formula mass can depend on whether it is hydrated or anhydrous. Write your answer in your notebook so you know how to make the solution in lab.Practice Problems:Question 10 out of 1 pointsA galvanic cell is composed of one half-cell consisting of an aluminum metal electrode in 1M aluminum nitrate, Al(NO3)3, and the other half-cell consisting of a nickel electrode in a 1M nickel nitrate, Ni(NO3)2, solution. When the two half-cells are connected by a salt bridge and the electrodes are connected by an external wire, identify which statements are true about the cathode: (Choose allthat apply.) Selected Answers:[None Given]Answers:It is the site of oxidation.It is the electrode toward which metal cations migrate in the solutionIt is the electrode made out of aluminum metal.It is the electrode made out of nickel metal.ResponseFeedback:Since Ni2+has a larger reduction potential than Al3+,the nickel ions are reduced and the nickel electrodeis the cathode. See the diagram on p. 389 or one ofthe animations on the internet for what processes take place at the cathode and anode.
