Electroplating chemical mishap Answered
I figured it would be cool to quickly electroplate some stuff. Since I was lazy, I only used what I had on hand [block of zinc, vinegar, muriatic (hydrochloric) acid)]. The zinc ingot was taking too long to dissolve in the vinegar, so I added about 30 mL of hydrochloric acid. A couple hours later, I was electroplating fine. After two weeks of normal zinc chloride electroplating, the acid suddenly took on a nasty dull brown/yellow amber shade and a ton of white bubbles formed around the zinc (still in the acid). Can anyone tell me what happened?
