Hi everyone. I need your help! I'm about ready to order gold chloride from sigma in Canada. Would someone more knowledgeable than myself please confirm that this GOLD(III) CHLORIDE TRIHYDRATE, 99.9+% CAS# 16961-25-4 is the correct gold chloride to order for the making of Gold Chloride Solution for making Colloidal Gold? I cannot order from Salt Lake Metals as they cannot deliver to Canada. Thank you in advance.
