A galvanic cell was constructed where one electrode was a Cu²⁺(aq)|Cu(s) electrode and the other was an M²⁺(aq)|M(s) electrode. The potential difference between the two electrodes was measured to be 1.73 V with the M²⁺(aq)|M(s) electrode being the more positive electrode. What is the potential of the M²⁺(aq)|M(s) electrode with respect to the standard hydrogen electrode?

Data: E°(Cu²⁺(aq)|Cu(s)) = +0.34 V

A galvanic cell constructed using an X⁺|X electrode connected to a standard copper half–cell (as used in this experiment) was found to have a cell potential of 0.45 V with the X⁺|X electrode being positive with respect to the copper electrode. Where on the number line below would you place the X⁺|X electrode?

Which of these cell diagrams correctly represents a cell in which this reaction is happening?

Zn(s) + 2Ag⁺(aq) → Zn²⁺(aq) + 2Ag(s)

In electrochemistry, the anode is defined as:

AB03E07

Nitric acid is a strong acid. This means that ________.

In this experiment you will draw graphs of temperature vs. time showing how the solution temperatures vary before and after mixing. An example is shown below.

From which point on this graph should the temperature of the mixture be recorded?

Calculate the amount of heat required to raise the temperature of 825.8 mL of a solution from 22.4 °C to 40.4 °C if the solution has a density of 1.04 g mL^–1 and a heat capacity of 4.08 J K^–1 g^–1.

To calculate the heat absorbed by the solution you:

How do you determine the mass of solid NaOH added to the solution in the calorimeter?

In part A of this experiment 60 mL of 1.0 M NaOH is mixed with 50 mL of 1.0 M HCl. Which one of these statements is true?
