(a)
Interpretation:
The reduction half and oxidation half-reaction of copper is to be stated.
Concept introduction:
Electrolytic cell is a setup in which electricity is required to carry out a non-spontaneous and not feasible reaction. In an electrolytic cell two electrodes are used. One is anode and other one is cathode. Anode is positively charged and cathode is negatively charged.
(b)
Interpretation:
The electrode at which two different half reactions are taking place is to be stated.

This experiment is more about understanding the colligative properties of a solution rather than the determination of the molar mass of a solid. a. Define colligative properties. b. Which of the following solutes has the greatest effect on the colligative properties for a given mass of pure water? Explain. (i) 0.01 mol of CaCl2 (ii) 0.01 mol of KNO3 (iii) 0.01 mol of CO(NH2)2 (an electrolyte) (an electrolyte) (a nonelectrolyte)arrow_forward5. b. For Trials 2 and 3, the molar mass of the solute was 151 g/mol and 143 g/mol respectively. a. What is the average molar mass of the solute ? b. What are the standard deviation and the relative standard deviation (%RSD) for the molar mass of the solute ?arrow_forward
