Friends, this test is for tin chloride or stannous from mineral soil. What metal do you think it is?

 

[Martijn]

Very likely copper. Nice brown false positive.

There could be a trace of purple, but very light.
Is that blue syringe your stannous with yellow solution in the tip?

You're testing a SOIL sample? You could have so much stuff mixed in there, the test is meaningless.

Stannous is only useful for processed metal dissolved in acid. To test soil with a high metal content, you need a proper assay to determine what's in it.

First I acid washed the soil.
I boiled the soil with nitric acid to remove copper and other harmful substances from my soil.
Then I did aqua rgia. Then I took a stannus test, which was dark brown.
Is this gold?

Please answer my question.
Is this the same soil you have been working with all the time?
