Excess Hg salts will be reduced to the element



By what, the NaOH addition?

No, by the Aluminum.

2 Al + 3 Hg2+ -> 2 Al3+ + 3 Hg

Does anyone have any information as to the amalgamation rate using HgI2?  I don't remember from where but I heard that using HgI2 'substantially' increases the time required for amalgamation.

EDIT:  In addition what would be the effect of the halogens in the reaction?  Could the iodine cause any problems(side reactions)?

Yes, the information is available using TFSE.

Sorry boss  :(  ... come to think of it it was one of your posts that told me that.  I just couldn't find any trials that gave a specific estimate as far as time.  I'll search harder.

The counterion (halogens etc) will not have any effect on the reaction, the only difference is the solubility of the Hg salt.

Thanks chief, with all of the help I have been given and with most of my materials aquired I am finally ready to begin micro-scale experimenting.  Expect some write-ups in the future from little ol' Flip.

"Swim recorded an actual amalgamtion time, it took 17 minutes(.5g mercury blob, 30g Al). The basic procedure is to put a plastic dish on the old balance, zero it, and poke at a mercury blob until about .3-.5 grams is weighed out, then dump it into some 2% I2 tincture, the kind you buy at walmart.  I can't verify that HgI2 is formed, but I have successfully amalgamated using this procedure:
300ml methanol and 300ml of water are placed in an erlenmeyer flask with 20-40g of aluminum.  The tincture is dumped on top of it, and the amalgamation proceeds for about 30 minutes (I use 1" inch squares, thrown in the coffee grinder)..."

it's bee-n a while since SWIM's touched the mercury, but...

.5g mercury blob

, how are the bees measuring this? a scale is a good start, but, how should it bee handled? it's toxic...no?

My schwartz is bigger than yours!  :P

Just use excess Hg it will help to convert the tincture faster.
