Extraction of Tin and Copper by Acid Leaching of

Tin exists as a dissolved species across a small range of potentials at around 0V, or if the pH is less than -0.42 in the acidic region as shown in the diagram. If pH is greater than 12.6 in very alkaline conditions tin is found to exist as a dissolved species. For the remaining pH range (-0.42 pH 12.6), the tin exists as the solid stannous oxide.
