The minds of people today and the ancients actually in every daydream or wishful thinking would want rich, if the ancient people who called rich if you have a lot of money and gold, if today other than gold is still a lot more in got what is it? Everyone knows, the mind wants to be rich by making gold has happened in ancient times, so many scientists try to make gold by cooking sand with livestock urine, yes of course the result is not gold though the color yellow, because gold can not be synthesized with ordinary chemical reactions
Yes the name is human, I also want to rich with making gold rich minds of ancient scientists ha .. ha .. but when we make gold from chemicals, precisely golden rain from the reaction is quite famous in chemistry, the deposition reaction.
To make fake gold (Fake Gold Rain) we need the following tools and materials
500 ml enlemeyer glass
KI solution 1 M
Solution Pb (NO 3) 2 1M
1. The first we prepare a KI solution of approximately 200 ml and we input into enlemeyer. This solution is not absolutely 1 M, but it can be with other concentrations expected to precipitate with a solution of Pb(NO3)2
2.After that, we add the solution Pb(NO3)2 slowly by using the pipette as in the picture below until the yellow deposits formed.
