Electrochemistry glycerin optional???

[no1special]

When I watched Steves video on the deplating cell he adds a qtr tsp of glycerin the to the acid. I have read sever other post even by him saying that this was optional, but have not been able to find any info on why. I was just curious as to what the pros/cons were on using it or not.

The glycerin is not needed, its use was thought it could be helpful In the crystal growth, but it was later determined that it was not needed.

well you are right you can learn more about it from reading the forum than you can from asking the question.
