Q1. Shade the correct answer (T for True and F for False) (30 points): SCOTC 1 2 3 4 5 6 7 an The pH is an index for the acidity and alkalinity of a solution. The acidity and alkalinity of a solution depends on the specific metal of interest. The strong acids have the highest values of pH.. T The strong bases have the lowest values of pH.. T All metal oxides are soluble at any pH values. T Oxygen dissolved in water is one of the primary causes of corrosion in the oil field. T Oxygen is a strong oxidant and reacts quickly with metal. T The maximum amount of oxygen in water is only 8 ppm, so the mass transport of T oxygen is the rate limiting step in oxygenated non-acidic environments. Small concentration of dissolved O, can increase the corrosivity of C0, and HERGER F F F F F F F VI IL F 8 F 9 HS gases. F 10 Oxygen can cause corrosion at concentration as low as 5 bbp in boilers.
