Thank you Shark
Sweet! Good to know. I was wondering where that would go.
Even Pewter works fine.
Would be best if you knew the exact makeup of the pewter though I assume?
Getting started it may be more important that the stannous chloride works. Later, making it consistently can help determine, to a slight degree, how much gold is in the solution. For this the use of standard gold solutions and consistently made stannous could be more important. The way I work most often, knowing the gold is there or not is more important than knowing about how much is there.
Not important for the functional test as long as there is ample Tin.
Welcome to us.
While using a Q-tip is often used to test solutions, problems arise when the solution you are testing is dirty. Dirty solutions can mask a positive or a negative stannous test. This is especially true with dirty solutions from aqua regia and e-scrap. Plus, a Q-tip has a plastic stick which the cotton swab is wound on to. Recovering values from these used Q-tips requires burning these often smoke intensive plastic sticks. And finally, a Q-tip can easily absorb a milliliter of solution, for a concentrated solution this can be costly.
