Reactions of Copper
Due: Wednesday January 18, 2013 Start of Class
Obstruct: 5
Goal / Security:
Purpose:
1 . Observe some chemical reaction of copper and its particular compounds. 2 . Write term and formula equations to symbolize these reactions.
Safety:
1 . Wear glasses and a lab kitchen apron or cover.
installment payments on your Tie back again long frizzy hair and secure loose clothing before dealing with an open flame. 3. Rust substance; avoid contact with skin area, eyes, and clothing. Tend not to inhale vapour. 4. Poisonous or noxious vapors. Utilize the fume bonnet when given to do so. Usually do not inhale steam.
Equipment and Materials:
5. 250 cubic centimeters beaker
* 1 . 5 g Copper
* Scooper
* Size
* Goggles
* Nitric Acid
* Fume Engine
* four hundred mL beaker
* Tap water
* Sodium Hydroxide
2. 25 mL graduated cyndrical tube
* Mixing Rod
* Distilled Water
* Heater
* Tong
* Sulfuric Acid
2. 100 cubic centimeters graduated cyndrical tube
* Zinc
* Hydrochloric Acid
Observations:
1 . Addition of nitric acid to copper:
* Remedy turns green
* Produces orange gas
* Copper Nitrate is created
2 . Addition of sodium hydroxide to copper(II) nitrate:
* Green crystals liquefy
* Over cast appearance
3. Heating copper(II) hydroxide:
2. Solution turns black after stirring
2. Water together with copper
four. Addition of sulfuric chemical p to copper(II) oxide:
* Solution converts clear green when stirred
5. Addition of zinc to copper(II) sulfate:
* Copper is formed
Data and Calculations:
Initial Mass of Beaker: 107. 3g
First Mass of Copper: 1 . 5g
Last Mass of Beaker and Copper: 108. 4g
Mass of Copper mineral Recovered: 1 ) 1g
% Y = Final mass of Cu/Initial Mass of Cu back button 100
1 ) 1g Copper/1. 5g Copper x 75 = six. 33%
