Unformatted text preview: Experiment #6: Stoichiometry and the Ideal Gas Law By: Yueyue Shen I nstructor: Hasan Arslan Due Date: 10/22/09 Purpose: Devise and implement a procedure capable of determining the identity of an unknown nitrite salt. Procedure & Observation:- Fill the Erlenmeyer flask with water.- Use the pipette bulb to force the water from the flask to the beaker, filling the tube with water.- Mass of the unknown salt: 1.195g- Dissolve the salt with 3 ml of distilled water.- Get 25 ml of sulfamic acid, the pour the acid into the Erlenmeyer tube,- Slide the tube containing the salt into the Erlenmeyer tube (the Erlenmeyer tube should contain 60-75ml of distilled water and 25ml of sulfamic acid).- Tilt the tube with the salt, so the reaction can occur.
