So I tried to do electroplating at home, and admittedly I didnt do enough research due to curiosity getting the better of me. So I used a chunk of brass as one electrode, and a quarter as the other, I put them both into a solution that was baking soda and water, I was trying to plate the quarter with bronze, and I realize now I should have used a different electrolyte solution. However, now my solution has turned a blue color and im not sure exactly what happened, I think the zinc reacted with the bicarbonate from the baking soda, either that or I made copper carbonate, Im honestly a bit lost and was hoping for direction with it.

Blue in such cases is almost always copper.

Generally speaking you can't electroplate with an alloy (like brass), you can electroplate with a single metal (like copper).

For copper plating you need low pH, (bi)carbonate bath won't work.
