Spirits of Salt

pappa_golf

Spirits of Salt which I am lead to believe is a form of Hydrochloric acid (according to wiki)

the spirit of salts will be used to remove rust from a tank , can anyone tell me a common (household possabley) that will neutralise the stuff so that it stops its cleaning/eating action

I,m not after "alternate" products to do the cleaning job , just a common neutraliser for the product


data sheet here https://www.e-secure.biz/documents/897FG425JU/Spirits%20of%20Salt.pdf

never did chemistry at skool.

thanks

the one I used in the past was Oxalic Acid. Hydrochloric is not easy in the eyes or lungs.

what did you use as a neutraliser?

the datasheet for one simular to the one I am using is linked above

the best answer I can find on the web is household bleech ,

If you are not sure of the chemistry involved or have full instructions of how to use the products I would look for a different solution. I don't know the concentration of the product you are proposing to use but hydrochloric acid is a strong acid and should be treated with care.
To neutralise an acid you need an alkali. In labs sodium hydroxide would probably be the most common option. However depending on the concentrations the reaction can be violent.
Without clear instructions - including safety precautions I would not advise going down this path.

the concentrate is in the PDF , 500g would be added to approx 8l of water in stages

Quick lime or slaked lime in solution

what is Quick lime or slaked lime in solution used as in a domestic household?

We did not neutralise it. We put some in a tub and added the parts (stainless steel and some were plastic, non were rusty, but had to follow a process), then rinsed the parts many times. It was even poured down the drain after each use.

The other one I believe is phosphoric acid is the main ingredient in rust converter used on cars.

hydrichloric acid you can also nutralise it via chalk, or marble (the stone, not glass balls ), or calcium carbonate or lime stone - all the same stuff. This generates carbon dioxide, calcium chloride (used in food products) and water. You do not have to balance solutions out exactly like an alkaline just put a large enough lime stone rock in it till it it stops fizzing as a little bit of chalk wont kill you, but does make hard water.

What kind of tank, and could you not patch it and put a waterproof membrane inside?

thank you , I have been advised that in the case of a metal tank (I am working on) that the mix may still be in the joints/seams even after washing , and that it should be neutralised before its final use , as the mix will continue to work and/ or continue to eat into the metal

In the home, Sodium bicarbonate or baking soda is an easily obtainable alkali that will react with acids to release CO2

I have a degree in chemistry (obtained 35 years ago and not really used since, but this is pretty basic stuff).

I would not recommend using an alkali to neutralise hydrochloric acid in a domestic setting. Your best bet is to let somebody who know what they are doing take on the task, but if you insist on doing it then rather than attempt neutralisation I would simply wash off the acid multiple times. If you can get hold of some litmus paper you can tell when it's back to neutral pH.
