Question
In the electrolysis of water, which gas (H_1 or O_2) will be collected at the cathode? **Questions 5-6 refer to the galvanic cell described below** A galvanic cell based on the reaction 3Ag^+(ag) + Al(s) rightarrow 3Ag(s) + Al^3+(aq) is constructed from two half-cells: one with a silver electrode in 1.0 M AgNO_3 and an aluminum electrode in 1.0 M Al(NO_3)_3. The two half-cells are connected with a wire and a salt bridge filled with 1.0 M Na_2SO_4. As the reaction proceeds, which electrode (Ag or AI) will decrease in mass? At the end of the reaction, which half cell (Ag^+//Ag or Al Al^3+) will contain sulfate ion? Based on the activity series in your textbook (Table 9.6, page 338), which of the following metals will not react with a strong acid? There may be more than one right answer! a) Mercury b) Chromium C) Copper d) Cadmium. What is the value of E degree_cell in volts, for the galvanic cell produced by connecting the following half cells? Enter your answer to the thousandths place. Mn^2+(aq) + 2e^- Mn(s) E degree_red = -1.185 V In^3+(aq) + 3e^- In(s) E degree_red = - 0.3382 VExplanation / Answer
5)
Al(s) will dissolve in solution as Al+3
So Al electrode will decrease in mass
