AI Article Synopsis

  • The study calculates the distribution of various chromium(VI) species in water, including CrO4^(2-), Cr2O7^(2-), HCrO4^(-), and H2CrO4, across different pH levels.
  • The total chromium(VI) concentrations examined range from 10^(-2) to 10^(-6) M, highlighting the impact of dilution on species distribution.
  • The pH levels considered in the calculations range from 1 to 8, indicating how acidity affects the presence of these chromium species in solutions.

Article Abstract

The distribution of the chromium(VI) species CrO(2-)(4), Cr(2)O(2-)(7), HCrO(-)(4), and H(2)CrO(4) in aqueous solutions with total chromium(VI) concentrations of 10(-2)-10(-6)M at pH 1-8 have been calculated.
