I have seen some say a dd acid to peroxide for initial solution, but when refreshing, add a liquots of hydrogen peroxide to Piranha mixture.=A0 Is that ok?
=A0
We recently had an incident when Piranha came in contact with ferric chloride and instantly reacted
violently Was this due to the metal, the fact that both are oxidizer s, both, or something else?
=A0
I have read that neopr ene gloves should always be worn.=A0 True?
=A0
What type of glass is appropriate for containment?< /p>
=A0
