Hello--
A Wiki search states...

"The chemical equation for bleach and hydrochloric acid is as follows:
NaClO + 2 HCl ----> Cl2 + H2O + NaCl. In other words, sodium
hypochlorite and hydrochloric acid make saltwater and chlorine gas. ...
Chlorine gas is highly reactive because the bond between the two
chlorine atoms is weak..."

(According to various news outlets, Syria's Assad regime is using
chlorine gas or
another related weaponized chlorine compound against civilians, causing many
casualties.)

Under NO circumstances should you mix these chemicals to use an an
experimental
PC-board etchant!
