Hcl?? Urgent

[dirk_brijs]

went out to buy hydrochloric acid today.
Bought 5gl now when I got home the label (which I should have checked there though??) said HCL?
Isnt HCL Hydrogen Chloride? How can this be isnt this supposed to be a gas?
So I asume the thing I bought is HCL mixed in water so Hydrochloric acid (H3OCl) afterall right or not?
Now to go ahead with my anti phosphate and copper treatment I should dilute this to a 10/1 ratio right? So 20Gl of water and 2Gl of H3OCl?

guys can anyone help would like to start with this asap but would like to check here before I start??

You do have hydrochloric acid there... I don't know about the dilution ratio you need though.

Make certain you have rubber gloves, eye protection, etc. Also, there is an old adage: "Do as you oughta, add acid to wata" - meaning NEVER add water to concentrated acid, it can boil up on you.

I have no idea the dilution ratio of what you trying to accomplish though.....the product you have may be muriatic acid which is only about 31% HCL. Very often, people mean a 10% solution of THAT, which is actually around 3% HCL

The 1 part acid to 10 part water refers to using muriactic acid with is around 30% - 40% HCL depending on the product your purchase. This solution is used to remove phosphate and heavy metals (copper) from rock.

Hydrochloric acid is the same as muriatic acid? Or am I wrong informed?
I presume too what I have can only be H3OCl as HCL is suposed to be a gas or am I wrong here again?
Not sure about the strength of the muriatic acid but arent they pretty standard as I cant seem to find anything on the label?

Muriatic acid is HCL and is what you want to use. Most muriatic acids range between 30%-40% HCL which is fine. There should be a label on the product that states what percentage HCL is in it.

All Hydrochloric acid, no mater what the strength, is also Muriatic acid, be it 0 % or 38 %. The highest you can normally buy is 38 %. When it gets to 40 % it is called Fuming Hydrochloric acid, as some of the Acid in solution goes into a vapor state and gives off HCl gas. Thus, it has a very high evaporation rate, which is hard to control when you open the bottle.

The term HCl is really improper as HCl is a gas. When that gas enters a aqueous solution you get H3OCl.

HCl ( gas) + H2O ( water) → H3OCl (aqueous)

Same as only written differently

HCl + H2O → H3O+ + Cl− (which is the more correct of the two)

You have to know the strength of the MA before you can figure out what its % solution is. 10% is also quite commonly sold in stories, which needs little dilution , i.e, 3 :1. The more powerful industrial type is 30 - 34 % need the 10:1. As Jay pointed out, in short, you are looking for a 3% solution. For cleaning parts of calcium build many use straight 10 % HCl. And also as Jay pointed out, ONLY add Acid to water and not the other way around. This will reduce the exothermic reaction.

There HAS to be a % on the bottle.
