Brown Particulate Comparison between Baking Soda and Baking Soda w/ Vinegar

I compare the brown particulate that accumulates from hydroxy production between using baking soda and baking soda with vinegar as the electrolytes.



My Observations:

The baking soda only has considerably more brown particulate than the mix of baking soda and vinegar.

The baking soda only particulate is slightly darker than the mix.

I think someone is right about Baking Soda and vinegar as a mix. Playing with the receipe should yield better results.
