There's this strange (and unknown to me) turn of phrase:
"[...] and covered with 30 ml of (1 + 5) hydrochloric acid [...]"
Anyone know what (1 + 5) hydrochloric acid means?
Bear in mind the document was written in 1963!Mr.Fluorine - 9-1-2023 at 10:44
I just think it means that you should use hydrochloric acid that has a concentration of about 16%, 1 part HCl to 5 parts water.unionised - 9-1-2023 at 10:46
1 part conc HCl. 5 parts water
So, very roughly 6% or 2 Molar.blogfast25 - 9-1-2023 at 14:01
