Thread: Where to find hydrochloric acid?

godless me only knows how I got into this, but it's through the electrolysis of sea water (salt water), that you get Chlorine / Sodium Hypochloride / chloride / Hydrochloric acid (whatever) and Sodium Hydroxide.

One is an ACID and the other is an ALKALI.

Same base substance.


So remember if you even just happen to accidentally swallow a liter or so of hydrochloric acid, just follow it with a kilo of sodium hydroxide.

Neutralises each other perfectly.

Simple chemistry: 1 liter HCl + 1 Kg NaOH = becomes results in

Pickling of steel

One of the most important applications of hydrochloric acid is in the pickling of steel, to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques.[3][5] Technical quality HCl at typically 18% concentration is the most commonly used pickling agent for the pickling of carbon steel grades.
Fe2O3 + Fe + 6 HCl → 3 FeCl2 + 3 H2O


Also hydrochloric acid becomes ruined by sunlight.
