Subject: saving FeCl3 solution

From: "microsoftwarecontrol" <microsoftwarecontrol@...>

I bought solid FeCl3, in small ball shape.
I add water to get pcb etching solution.

I found used FeCl3 solution will become
two parts: green, transparent liquid and
yellow solid at bottom.

As I understand, green solution should
contain Cu ion from pcb.

Could I pour out green liquid and add new
tap water to renew etching liquid?
