2: Muriatic Acid: same questions, basically:

? ?How much, for how long, etc.

? ?Dangers?

Drained Pool (pending)!

How or what can I use to neutralize Muriatic acid/water pool ?

I plan to acid wash the in ground pool walls. While I'm busy there
(walls) the acid wash will pool at the deep end of the pool.

I would like to toss/pour something into the puddle that would
neutralize acid; until I can pump it out.

Thanks!!

Any base. Bicarbonate of soda is cheap and easy. If the mix fizzes and
doesn't stop you need more bicarb.

Have you ever worked with Muriatic acid, if not beware the fumes will
seriously damage your lungs, Muriatic is a fuming acid and there is no
way to avoid it, if you are in the pool likely the fumes will
concentrate and stay in the pool, A very good respirator is a must but
even that wont protect you 100%. It might be a job to pay to get done
and not subject your lungs to. Muriatic also eats galvanising off
pipes quickly, then they rust fast. I would not let acid sit in a
pool, but neutralise it or have it drain while being diluted with alot
of water. If pipes are pvc there is no issue but the drain may not be.
There is wrong and right way to do the job you need to research it.
Ive washed with muriatic and it made me sick for days from the fumes.

My neighbor had to fill in his pool , he said over years of cleaning
with acid the drain leaked and the pool would not hold water anymore,
bleach kills mold, soap might work, research before you clean it.

Tanks for the safety tips.

This is a shallow, 10,000 gallon pool. PVC pipes and sewer lines.

I'm being cautious and may hire the job out, but I now know more of
what to ask a company that would do the wash.

I'm leaning towards doing the job over a weekend....

Yes. I don't have a water table problem. My pool should not float out

No link (chemistry class). But, if you should add too much ammonia
there won't be a problem, plus it is cheap. The ammonia reacts with
HCl and produces a salt. You will get a (harmless) white smoke if
both liquids are close to each other. Properly dispose of any excess
muriatic acid--you really don't want this stuff laying around.

Muriatic acid can splatter, emit caustic fumes, corrode metal, cause
skin burns and blindness. It contains HCl, one of the strongest
acids. If diluted properly (adding acid TO the water), it becomes
less hazardous. Not a wise idea to have a bottle of it laying around.

I strongly disagree with your recommendation to ignore basic acid safe
handling. Adding acid to water is always safer because the acid is safely
dilluted as it is poured. Adding water to acid (especially a granular form of
an acid such as sodium bisulfate but also for liquid/aqueous acid solution)
results in working with a very strong solution, which isn't something you want
to mess around with or risk splashing.

Yes it is true that pure water added to muriatic acid (which contains water by
definition) will not cause a reaction in itself, but that is beside the point
made for safe handling. Treat muriatic/hydrocholoric acid (and any strong
acid) with a great deal of respect. I would strongly recommend wearing acid
safe gloves and a mask. One little splash of a drop can do a lot of permanent
and painful damage to an eye, to say nothing of other body parts.

If that is the case than you are working with fairly weak HCl solution!! What its strength
in moles?

The HCl I work with regularly would put dissolve skin fairly quickly. I stand by all of my
comments regarding acid handling safety. For many people, swimming pools is the first time
they encounter such chemicals, and there are some things that are best not learned first

The rule of acid to water is a good one for the non chemist, and
usually for chemists as well. It is a general rule of thumb that is
just easy to remember and follow. If you understand the
characteristics of what you are working with, then you can bend the
rules, but with the proper techniques and understanding. The unwise
should never add water to acid. It is clear from most of the posts,
that the general rule of acid to water should be followed by just
about eveyone responding to this post.

All concentrated mineral acids develop heat when mixed with water. The
problem is that some acids, like concentrated sulfuric acid are prone
to a highly localized and large release of heat of mixing. The
dissolution especially in this case becomes violent, with subsequent
violant spattering of acid due to localized steam generation.

Do chemist ever do the reverse with acids? Sure, but not before
carefully thinking about how they will control the mixing conditions
and adjusting for the consequences.

Right, but that's added to an entire full pool of water! Different story when
concentrated acid is touching something directly.

Goes back my question originally (OP); neutralize the acid in a pool
of water. While I work I don't want etching acid sitting there, at
the pool bottom.

I'm buying 5 lbs of soda ash, just for this puddle of water.

Makes sense, but you don't need to over do the soda ash either. A too basic
solution will do a lot less damage to concrete and grout than a too acid solution,
but both are harmful to finishes and your health if too strong.

If this acid has been in the bottom of your pool all week I doubt
there is really much acidity left anyway and you probably do have a
"ring" in the pool.- Hide quoted text -

Acid reacts with lime, Lime is in concrete-mortar, acid eats metal
drains, maybe most pumps, definatly boiler linings and valves. Acid
can destroy anything metal. So go Clean it with acid tomorrow, and
reduce plumbings mechanical life by 90% I hope the main drain isnt
galvanised, thats hard to replace, often meaning a new pool, or
filling the old one with dirt as my neighbor did.

I'll be frugal. An earlier link suggest two pounds of soda ash would
neutralize one gallon of acid. My solution will be diluted 1 acid
4-6 water, spray on the pool walls and flush with a water hose.

The puddle that forms would not need much soda ash... enough to stop
the "fizzing". The water hose would be also filling the puddle at the
bottom of the pool... more dilution. Then I can pump it out to
sewer.Thanks for the comments.

But the job hasn't started yet. I can't wash / spray with acid in 30
mph winds

Litmus paper will verify if you neutralise it. Acid may not make a
difference in looks, before you experiment you should test a section.
There are many other totaly safe ways to clean anything. As I said my
neighbor had to fill in with dirt his $100,000 pool from acid ruining
the main drain. How about your pump and boiler, etc., acid eats metal.
Get a garden sprayer to apply whatever you use and do a test, and
remember the Fumes will stay in the pool with you, even with a wind.
You are messing with nasty stuff that has burnt my lungs and ruined
the galvanised coating off of conduit that rusted a week later, but
was ok for 30 years. Dont kid around with acid, it bites back hard.
