Question

The potential of a corrosion cell composed of nickel (anode) and a hydrogen electrode (cathode) immersed in a 0.3 M NiCl2 solution at a temperature of 70 ℃ is measured to be +0.220 V. What is the pH of the solution?

Answer 1

0.314

Step-by-step explanation:

The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution.
