- Solid
- Green/blue color
- Fragile
- Thick Bottle

- thin
- looks like crystals
- small
- soft
- clumpy
- turned green
- the chemical sunk
- some of it was floating
- turned a light blue when it was stired
- turned black when tin foil was added to it
- fizzled
- bubbles rose
- tin foil turned red in cooper chloride
- peices of thetin foil came off
- tin foil fuzzzed
- breackable
- flexible
- cooper chloride turned gray
Water temp before cooper chloride was added: 20 degrees
The cooper chloride stayed over nite and went back to a blue color beacause the tin foil desinagrated.
The tin foil disappered and now on the bottom in the beacker it looks like sand (tin foil) copper seperated from the chlorine. The bootom is a brown, blue, and also teh color purpleis on the bottom.
The chlorine then went through the paper and the sand did not it stuck to the paper. And it turned purple and hardened to the paper.
When we put the other chemical in with the sand and chlorine after seperating them.The cooper cloride turned white then blue then green. The sand seemed to fizzle to the top in little air bubbles. Like when you put eater egg colorings into water and tehy fizzele is disinagrat.
