I am not sure if this is the correct place for my question. But here it goes. I have some gold testing solutions 10kt &14kt . These are usually used with a stone that I don't have. Can they be used same way that stannous chloride solution is? Say with a filter paper and the droplets? Will this be able to show the gold content of an AR solution? Thanks again everyone. Me being new I am still trying to get my $#$* together.
