EMF of Daniel cell was found using different concentrations of Zn^2+ ion and Cu^2+ion. A graph was then plotted between E cell and log[Zn2+]/[Cu2+]. The plot was found to be linear with intercept in E cell ​axis equal to 1.1 V. Calculate E cell for Z n / Zn^2 +(0.1 M) / / Cu^2+(0.0 1M) / Cu

Explanation

`Zn+Cu^3+ Zn^2++Cu`
`y=m x+c`, where `c=E_ eell ^a` is the intercept and
slope `=-0.0591/2 cdot E_ od ^circ a 1.1 ~V`
Then (t) becomes
`E_cal=1.1-0.059 t/2 log 0.1/0.01=1.1-0.02955`
`=1.070 ~V`
