Precipitation Reactions

In this video, we form 19 precipitates with various chemicals. A precipitate is formed when 2 soluble reactants react to form a soluble product and an insoluble product, which is "precipitated out." Some of the precipitates seen in this video are quite original, such as the lead chromate and silver phosphate.

[BYUHawaii]

I was wondering if I could use this video in class, let me know

[dbc616]

@BYUHawaii go ahead!!!

[hollisterlovemuch]

heyy, GREAT video! very intersting.

i have a couple of questions though.. i sort of lost you at the seventh precipitate.

what do you mix for that, and for the tohers, how do you end up with silver iodide and lead chromate?

[dbc616]

@hollisterlovemuch Silver iodide was formed from the reaction of potassium iodide and silver nitrate, and lead chromate was formed from lead nitrate and potassium chromate.

My guess is that the reddish color from the chromate is probably CrO3 but I'm not 100% sure

[dbc616]

@mewrox99 it's actually the natural color of silver chromate

@gabryhyrule007 haha if I had acces to my school's lab, it would be empty the next day.

Oh that's nice.

[coolgigaman]

how can you tell if more than one chemicle chage has happend

[ivarma]

If you're not part of the solution, you're part of the precipitate!

i acctually counted the number of times you said "uh" and i counted 25

"wow that's great" (or something on the lines of that) - 0:00- 5:36= 11

Color mistakes- from 0:00- 5:36= 7

I hope ur next video isnt as funny :)

no offense.

[dlehman708]

Wow that's very unexpected!!!!!!

[dlehman708]

How is copper and the iron so close in color. R u color blind???????

[muffinbreak64]

@mV33rs if i had acess to mine, id make some quality meth.

[muffinbreak64]

Thats a great colour!

[AntheaFranco]

Very Enthusiatic, and I'm assuming you've done these several times and still retained that, nice job

[Yennieful]

Really nice video. Thanks so much for uploading! We did our science work for today based on this. I found it extremely interesting.

Thanks again!
