The standard free energy change at 25C, ΔGo, is equal to (-38.7) kJ for
2X(CN)63-(aq) + 2I-(aq) → 2X(CN)64-(aq) + I2(s).
Calculate the standard potential for this reaction. Normally, X is Fe. Here it is some unknown metal, allowing for somewhat random values for ΔGo.
An unknown compound X, is thought to have a carboxyl group with a pka of 2.0 and another ionizable group with a pka between 5 and 8. When 75 ml of 0.1 M NaOH was added to 100 ml of a 0.1 m solution of X at pH 2.0, the pH increased to 6.72.
Prepare 1.00L of a pH~12 buffer with a total phosphate concentration of 0.050 M.You have at your disposal the following compounds
