Classify the compounds present in the mixture

Reference no: EM13196006

A solid sample (0.3082 g) could consist of NaOH and/or NaHCO3 and/or Na2CO3. (There may also be inert filler present.) This sample was combined with 25.00 mL water and titrated first to the phenolphthalein end point, requiring 22.57 mL of 0.08927 M HCl solution. The bromocresol green end point came at 39.50 mL titrant added, total. Identify the compounds present in the mixture and determine the percent by mass of each in the original sample. 1 Identity and % (wt/wt)= 2 Identity and % (wt/wt)=
