1. Chemistry Project Work Mavis Lau F.3A (16)

2. Name: Nitrogen Trifluoride Formula: NF3 Electron diagram: N F F F O O O O O X X XX XX X X X X XX X X XX X X X XX

3. Physical Properties Melting Point: −206.8 °C Boiling Point: −129.1 °C Physical state at room temp.: colorless gas Colour: colorless Density: 3.003 kg/m 3 (1 atm, 15 °C) 1.885 g/cm 3 (liquid at b.p.) Solubility in water: 61mg/l(0.021 vol/vol) Electrical conductivity: Poor

4. Chemical Properties Laboratory preparation: Wear safety glasses or goggles for eyes or face protection. Wear plastic or rubber gloves for skin protection.

5. Uses of Nitrogen Trifluoride an oxidiser for high-energy fuels and is used in chemicalsynthesis a fluorine source for the hydrogen fluoride anddeuterium fluoride high- energy chemical lasers

6. Potential hazard Inhalation causes breathing difficulties, chest pains, and nausea. It forms a hemoglobin complex, similar to carbon monoxide, and thus, is highly poisonous due to interference with oxygen transport in blood.
