Week31: Back on Track!

Okay After gettigng all my late work out of the way, i now can focus upon  THIS week's reflection.
We discussed the synthization of copper this week and even preformed it. I sadly wasn't  there everyday ( thanks to AP Exams....) so i don't think i truly understood the experiment.

We started with an Iron  Nail sumperged in copper chloride after weighing out  the copper cloride and adding water. Imediately the nail took on a Red color, assuming the nai lwas oxidizing, or rusting, we  set it in the  corner of the room and left it overnight. i thought it  was cool how  immediate the  change was. When we returned the next day,  the nail was covered in a  red... algae like substance, and  i was worried something was wrong becuase the water was a  urine  yellow color. we  removed the liquid from the   test tube and them removed the nail. the Algae stuff  decreased in size when removed from the liquid, and took on an even briger reddish hue. IT didn't look like rust anymore. we removed all we could from the liquid and from the test ube and offf the nail and Mr. Abud expalined this was what pure copper looked like.

IF the copper was not a solid, what was  the liquid now? We noticed th thee mass of the nail shrunk too, and we concluded  the liquid was  iron chloride, and not copper chloride. this  Synthesis of copper is a warm up to the snythesis of silver, which we'll do and make silver coke bottles next week i am truly excited for this!!
