Make Hydrochloric Acid

We show how to make hydrochloric acid from sodium bisulfate and table salt.

The synthesis is rather simple, we generate hydrogen chloride gas by mixing together 140g of sodium bisulfate and 60g of sodium chloride salt and then heating. 20mL of water can be added to lower the temperature required but this is optional. Hydrogen chloride gas will be produced. This gas is lead into distilled water to produce hydrochloric acid. Be careful though, hydrogen chloride is so soluble that the water will pull itself into the tube trying to absorb it. In the video i use an elaborate back-flow prevention system to prevent loss of the product.

Sodium bisulfate is available as a pH lowering chemical. 30mL of sulfuric acid may be used as a replacement if you have it. Although if you had that, you probably don't need hydrochloric acid.

"I want to play a game."

Thats all I could think of listening to this lol

my science class wanted to do an experiment with sulfuric acid and sugar however being a middle school we can not do this could you consider making a video of this reaction as there are none out there that are good are you working on or going to make a video explaining and showing this

Yes, I like this. I suspect the HCl I got at the hardware store is loaded with Fe contamination. I wanted to make some that I know to be pure. Following your instructions I can probably reserve my H2SO4 for other purposes. Your trap method is more sophisticated than what I envisioned too. Thx!

@hinno95 damn I have forgotten so much since last year!

@fdsdh1 To bad that it is: HCl and not HCL

[ZTrasher]

a big bug

[ZTrasher]

was there a bug in your ice?

[fdsdh1]

I'll just pop down to my local shop and buy some sodium bisulphate!

[fdsdh1]

HCL= Horrible Corrosive Liquid

[diegonikki]

uhh question do u have sulfur hexaflouride in you ?

[Akademee]

I thoguht I left the word "titration" back in high school -_-

@kdc43 Yeah, but you can't get acid from your stomach anyway
