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.

Lower pH by adding muriatic acid.


How can the ph level of a pool be lowered?

The pH level of a pool can be lowered by using a specific acid that is sold at pool supply stores. The acid is called muriatic acid, and it should be added to the pool while the water is circulating. About 1/4 gallon of the muriatic should be added per .1 part per million the pH needs to be lowered.


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.


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.


How much muriatic acid is needed to lower PH?

It depends on the pH level in the pool and the gallons of the pools, also how many ppm you want to lower it.


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 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.


How much muriatic acid in a 22oo gallon pool?

To determine how much muriatic acid to add to a 2200-gallon pool, you need to test the pool water's pH level using a test kit. Based on the pH level test results, you can calculate the amount of muriatic acid needed to bring the pH to the appropriate range, typically between 7.2 and 7.6. It's crucial to follow the manufacturer's guidelines for adding chemicals to your pool to avoid over-treating the water.


Can you use muriatic acid to raise the cyanuric acid level?

No, muriatic acid is used to lower pH and total alkalinity levels in pool water, not to raise cyanuric acid levels. To raise cyanuric acid levels, you would typically use cyanuric acid stabilizer or conditioner.


How do you lower the pH level?

To lower the pH level, you can add acidic substances such as vinegar, lemon juice, or citric acid. Alternatively, you can use pH-lowering chemicals specifically designed for water treatment, such as pH decreasers. Make sure to test the pH level regularly and make gradual adjustments to avoid drastic changes.
