consider the reaction between sulfite and a metal anion, x^2-, to form the metal, X and thiosulfate: 2X^(2-)(aq) + 2SO3^(2-) + 3H2O (l) --> 2X(s) + S2O3^(2-)(aq) + 6OH- for which the Estandard cell potential is +.90 given that the Estandardreduction potential for sulfite is -.57V, calculate Estandard reduction for X.
