Purpose: The purpose was whether to see if a element can either be a reactant or perhaps product in a chemical reaction, and if a new material would be produced due to reactions.

Materials:

- pyrex test conduit 13 x 100 millimeter

- 95 ml beaker

-- wire gauze, ceramic concentrated

-1. 0 M water piping (II) nitrate

-1. 5 M sodium hydroxide

-1. 5 M hydrochloric acid

-12 cm piece of aluminum cable

Procedure:

In the beaker, heat 55 ml normal water

make 3 marks by bottom to top on the test conduit that are one particular cm separate Add 1 ) 0 Meters copper (II) nitrate towards the first tag

Add 1 . 5 M sodium hydroxide to the second mark, and mix. Observe and feel the pipe for any heat released. place test conduit in the beaker, and turn off burner only if no more adjustments occur. The results you get obtain are copper(II) oxide and water. Turn off the burner and take out test pipe and great for two mins in room heat water. Add 1 . five M hydrochloric acid for the third mark and mix with stirring rod. Place the light weight aluminum wire in the test conduit and leave it until you can forget reaction can be observed. Feel and take notice of the tube for any changes. Remove wire and observe the copper formed.
