A sample is known to consists of NaOH, or NaHCO3 or Na2CO3 or possible compatible mixture of these, together with inert matter. With methyl orange, a 1.100 g sample requires 31.4 ml of HCl (1.000ml is equivalent to 0.0140 g CaO). With phenolphthalein , the same weight of the sample requires 13.3 ml of the acid. Calculate the percent inert matter in the sample
