Interpretation:There are two binary compounds of mercury and oxygen. The decomposition of
Concept introduction:For any compound, its empirical formula represents the ratio of atoms present in it. The most popular technique for evaluating the chemical formula of a compound first involves the calculation of the masses of its component elements.
The moles of each element concerning each other are calculated. These moles are changed into a ratio of the whole number, which is used for the derivation of the empirical formula of a compound.

- For a silver-silver chloride electrode, the following potentials are observed: E°cell = 0.222 V and E(saturated KCl) = 0.197 V Use this information to find the [Cl–] (technically it’s the activity of Cl– that’s relevant here, but we’ll just call it “concentration” for simplicity) in saturated KCl.arrow_forwardA concentration cell consists of two Sn/Sn2+ half-cells. The cell has a potential of 0.10 V at 25 °C. What is the ratio of [Sn2+] (i.e., [Sn2+left-half] / [Sn2+right-half])?arrow_forwardElectrochemical cell potentials can be used to determine equilibrium constants that would be otherwise difficult to determine because concentrations are small.
