Determination of FormaldehydeThese data are from a chemical experiment to prepare a standard curve for the determination of formaldehyde by the addition of chromatropic acid and concentrated sulphuric acid and the reading of the resulting purple color on a spectrophotometer. UsageFormaldehyde FormatA data frame with 6 observations on 2 variables.
