An analysis was done on 3 unknown samples (NaOH, Na2CO3 and NäHCU3) USIng each analysis and a single burette employing CONTINUOUS TITRATION with 0.0 ml. as INITIAL READING. Phenolphthalein and methyl orange indicators were used respectively and a standard solution of HCI with a concentration of 0.4875 N was used. Data from the analysis shown on the table below: FINAL BURETTE READING in mL Pp SAMPLE Мо A 5.8 5.8 12.6 15.8 15.8 24.7 NOTE: Sample A was analyzed first followed by Samples B and C. NO REFILL OF ACID WAS DONE. MW: NAOH 40, NazCO3 106, NaHCO3 84 WHAT IS THE IDENTITY OF SAMPLE A? O Nazcos ONazcoy and NaHCOy O NaOH NazCOs and NaOH
