A composition with corrosion inhibiting properties is provided that includes a first phosphate salt of at least one of trimetaphosphate, hexametaphosphate, or tripolyphosphate. A second phosphate salt of at least one of a disodium phosphate and tetrasodium pyrophosphate is also present with the first phosphate salt present in a weight ratio relative to the second phosphate salt of from 1-4:1. Upon dissolution from 0.1 to 5 total weight percent in a solvent a corrosion inhibiting solution results that is well suited for usage as a water conditioner in cooling systems. A process of protecting an iron containing metal from corrosion is also provided that includes exposing the metal to the solution. The corrosion of the metal over time is monitored to assure the protection of the metal.
