PART I Phosphorous acid, H3PO3(aq), is a diprotic oxyacid that is an important compound in industry and agriculture. A flask contains 65 ml of H3PO3(aq) A titration is carried out and analysis of the data showed that the first equivalence point was reached after 27 ml of 0.50 M NAOH was added to the acid solution. Answer the following questions: What was the initial concentration in M of [H3PO3), the phosphorous acid solution? What is the phosphorous containing component in the solution after the titration is over? Write the formula (use appropriate symbols for atom and don't worry about subscripts or superscripts) PART II 5 ml of 0.50 M HCI was added to the final solution in PART I. What is the major phosphorous containing component in the solution. Write the formula Given that pK1=1.30 and pK236.70, what is the pH of the solution? What is the [H*] of the final solution? enter scientific notation in number = exponent =

PART I Phosphorous acid, H3PO3(aq), is a diprotic oxyacid that is an important compound in industry and agriculture. A flask contains 65 ml of H3PO3(aq) A titration is carried out and analysis of the data showed that the first equivalence point was reached after 27 ml of 0.50 M NaOH was added to the acid solution. Answer the following questions: What was the initial concentration in M of [H3PO3], the phosphorous acid solution? What is the phosphorous containing component in the solution after the titration is over? Write the formula (use appropriate symbols for atom and don't worry about subscripts or superscripts) PART II 5 ml of 0.50M HCI was added to the final solution in PART I. What is the major phosphorous containing component in the solution. Write the formula Given that pK1=1.30 and pK2=6.70, what is the pH of the solution?
