UN 1076 – Phosgene HAZARDS: Phosgene is a highly toxic‚ irritating and corrosive gas. Inhalation can cause fatal respiratory damage. Phosgene reacts violently and decomposes to toxic compounds on contact with moisture‚ including chlorine‚ carbon monoxide and carbon tetrachloride. In case of skin contact: If liquid phosgene (below 8.2 deg C) contacts the skin or clothing‚ an inhalation exposure should be suspected. Hazards due to skin contact with the gas is unknown. Phosgene does‚ however‚ react

A known weight of food is placed in a flask with an organic solvent such as xylene or toluene. The organic solvent must be insoluble with water‚ have a higher boiling point than water and less dense than water. (Faichney‚ G.J. and G.A.

The purpose of Module 11A was to test for the presence or absence of a particular set of functional groups through the use of wet chemical tests. In this manner‚ Unknown A which was a colorless solution‚ was first tested with 2‚4-DNP which after mixing for a few seconds formed a bright yellow precipitate. Although this confirms the presence of either a ketone or aldehyde group‚ one simple chemical test does not completely specify the presence or absence of other functional groups. Therefore‚ a second

Using Selective Media to Monitor the Fermentation Process of Cabbage and Cucumber‚ for Fourteen Days Abstract: Introduction: The goal of the ecological succession lab is to demonstrate succession with the fermentation of cabbage and cucumbers. The cabbage will ferment into sauerkraut and the cucumber will ferment to pickles during fermentation process that will changes the species structure and the community of time. During the fermentation process we watched the pH become more acidic‚ since
