I'm going to be using a finings agent with a positive charge to remove negative trub from a solution (beer).
I would like to keep some chelated zinc in the solution - ideally zinc picolinate - so wondering what its charge is? I'm hoping it's neutral...
Depending on the answer, are there any zinc chelates that carry a neutral charge?
It's all so zinc can remain in the beer after fining to reduce the estrogenic effects of hops.
