- 4 mL of 10% TCA solution was added to 1 mL of serum and after mixing, it was waited for two minutes and filtered through non-phosphorus filter paper. 1 mL of the filtrate was taken and 13 mL of distilled water, 4 mL of sulfomolybdic acid and 2 mL of dilute SnCl2 solution were added and mixed, and after waiting for 15 minutes, the absorbances of the obtained solutions against pure water at 520 nm were read. If the function of the calibration graph obtained with 0.5-2.5 mg/mL standard phosphorus solutions is y= 0.245x + 0.107 and the absorbance value of the serum sample is 0.109, what is the amount of phosphorus in the sample?What would be the result of hexan-2-one or hexan-3-one on Brady's and Iodoform test?Which among the following statements is correct?
