Explain metaphosphoric acid solution

Reference no: EM13563474

A 10ml sample of pure orange juice was diluted with 40mL ofmetaphosphoric acid solution. Then 10mL of diluted juice wastitrated to an end point with 9.27mL of DCIP. A blank required .25mL of DCIP. A 1mg sample of pure ascorbic acid required6.52mL (after blank correction) of DCIP. What is theconcentration of ascorbic acid in the orange juice in mg/100mL?
