Muratic acid (Hydrogen Chloride) at a 10% concentration has a PH of -.5.

This is the concentration that is available for most houshold uses.

Lower pH by adding muriatic acid.


What is the pH level of muriatic acid?

Muriatic acid is a very strong acid. The pH will vary depending on the concentration of the acid. A 10% concentration (by weight) has a pH of around -0.5 while a 38% concentration has a pH of around -1.1. I found this information at: http://en.wikipedia.org/wiki/Muriatic_acid.


Are glass pH electrodes compatible with muriatic acid or solutions?

Glass pH electrodes are generally not recommended for use with muriatic acid or solutions with low pH as they can deteriorate and lead to inaccurate readings. It is best to use a specialized electrode such as a combination or ISFET pH electrode that is designed for measuring low pH solutions.


What is the common name for HCl when used to lower pH in swimming pools?

The common name for HCl when used to lower pH in swimming pools is muriatic acid.


Which muriatic acid should you use to replace stomach acid in your science experiment?

HCl in the stomach is (around 0.5%) and a pH of 1-2. You will need to make a solution of muriatic acid similar to that. If you have pH paper, you can figure it out.


How do you lower the pH in a pool?

Muriatic Acid....Be real careful though.


Is Muriatic acid good for pine trees?

Very small amounts of muriatic acid are mixed with water to lower the pH balance of the water and make it suitable for water pine trees. It is important to be careful and test the pH balance of the water because too much muriatic acid will kill the trees.


Which is better to use to lower Total Alkalinity level Muriatic Acid or pH Minus?

I tried both types of acid. The pH Minus (dry acid) and then the muriatic acid. I did not have much luck at all with the total alkalinity (TA) dropping with the dry acid. When I used the muriatic acid the TA dropped within a couple of days. So to answer your question I'd have to say the muriatic acid. It is much cheaper ($12 a case) at Leslie's Pool Supply and probably cheaper other places. The muriatic acid was also quicker and had better results.


What is the purpose of adding muriatic acid to pools?

In order to not cause irritation of the eyes and skin, the pH of the pool water should be between 7.2 - 7.6. Muriatic acid is added to the pool to lower the pH if it is too high.


Any home remedies for lowering the pH in a pool?

Add muriatic or hydrochloric acid.


Can you add muriatic acid to a pebble tec pool to maintain proper pH level or will it harm the pool?

Yes, you can use muriatic acid to control pH in a pebbletec pool. Added correctly (spread around the pool with circulation equipment operating) muriatic acid will not harm the pool. As a matter of fact muriatic or hydrachloric is the best thing to use but I suggest you dilute it 4 parts water 1 part acid for safety to you and your equipment


What are the ingredients for pool acid?

Pool acid typically refers to muriatic acid, which is a common acid used to lower the pH levels in swimming pools. The main ingredient is hydrochloric acid. It is important to handle muriatic acid with care as it is highly corrosive and should be diluted before adding it to the pool water.
