RE: [Homebrew_PCBs] what is sulfate of zinc and acidulated water andsaturated copper sulfate crystals ?

No good for high impedance or high voltage PCBs as it leaves a high resistance conductive film on the non track areas.
It is OK for logic level boards, but beware if the chip has an A-D converter.
