The reduction potential of two half-cell reaction involving iron is given. The value of K sp for iron sulfide (II) is to be calculated. Concept introduction: The relationship between reduction potential and standard reduction potential value and activities of species present in an electrochemical cell at a given temperature is given by the Nernst equation. The value of E cell is calculated using Nernst formula, E = E ° − ( R T n F ) ln ( Q ) At room temperature the above equation is specifies as, E = E ° − ( 0.0591 n ) log ( Q ) This relation is further used to determine the relation between Δ G ° and K , Δ G ° and E ° cell . Solubility product is applied only for those ionic compounds that are sparingly soluble. The product of solubility of ions is called solubility product and solubility is present in moles per liter. To determine: The value of K sp for iron sulfide (II).
