The following are some examples for corrosion that we experience in our day to day life. (i) Rusting of iron : Iron exposed to the environment forms a brown rust film on its surface. (ii) Water stored in aluminium vessel : If water is stored for a long time in an aluminium vessel, white spots

Here are a few simple electrochemistry solved problems along with their solutions: 1. Calculate the single electrode potential of copper metal immersed in 0.15°MCu2+ solution. E° for copper is +0.34 V at 25°C. Solution: By Nernst equation [latex] \mathrm{E}=\mathrm{E}^{\circ}+\frac{0.0592}{\mathrm{n}}\left[\log \mathrm{M}^{\mathrm{n}+}\right] at 25^{\circ} \mathrm{C} [/latex] [latex] \begin{aligned} & =0.34+\frac{0.0592}{2} \log [0.15] \\ & =0.34+\frac{0.0592}{2}(-0.8239)=0.3156 \mathrm{~V} \end{aligned} [/latex] 2. Calculate the electrode potential of
