Although exhibiting the beneficial characteristics discussed above, the solution of Table II maintains a high level of acidizing potential. That is, the pH level of the solution Is quite low, generally on the order of less than 1. Consequently, the Table II solution can perform conventional acidizing functions. The solution may, for instance, be used to remove oxides from metallic surfaces. Typical oxidation removal reactions for iron are disclosed in Equations (7) , (8) and (9) :
