Purpose: The purpose of this lab was to devise and implement a procedure involving the ideal gas law and a reaction between sulfamic acid and an unknown nitrate salt, in order to determine the identity of the nitrate salt. An unknown nitrate salt, MNO 2 (M being either Li + , Na + , K + , or Rb + ), was reacted with sulfamic acid so that the N 2 gas produced would displace an amount of water into a beaker, allowing the volume of nitrogen to be measured. The reaction followed this equation: MNO 2 (aq) + HSO 3 NH 2 (aq) → MHSO 4 (aq) + H 2 O(l) + N 2 (g) Observations: As the flask was tipped and the reactants mixed, bubbles violently formed The nitrate salt in the test tube slowly disappeared Heat was produced The water level in the Florence flask slowly decreased Water entered the beaker fairly slowly and continuously throughout the reaction Data and Calculations: The following data was collected: Solid 5387

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
