pH Levels

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.

You should check on your Total Alkalinity first and that should be the first thing added before pH Increaser. But without knowing all your readings it is hard to say exactly what is wrong with your pool water.

I assume it is an outdoor pool and that you are adding sufficient chlorine. Two reasons why it won't hold chlorine. . . 1. No, or insufficient, conditioner. Sunlight will destroy the chlorine if conditioner is not within 50-80ppm. 2. Phosphates and/or nitrates in the water. Get these checked at your local pool store - or send me a water sample if you can't find anyone to test.E-mail me for address.

If pH levels in your body are too high or too low, the body will not function correctly. Ideally, the pH of the blood should be maintained at 7.4. If the pH drops below 6.8 or rises above 7.8, death may occur. Fortunately, we have buffers in the blood to protect against large changes in pH.

PH is lowered by acidic conditions such as leaves rotting in the pool or the filter Your PH shouldn't bounce around to much but old water will lose its buffers. When you top your pool up check the tap water for the PH Balance to see if you are raising or lowering it by adding water. A high PH is obtained by adding chemicals to do just that but the area you live in might have very alkaline water which would cause that to be high.

You would do better in contacting United Chemical in California. I don't have an answer for this one. Never heard of the problem before. Possibly very or extremely high amounts of iron or magnesium.

There is NO way to lower TA without lowering pH. Slugging acid in a pool with the pump off will have EXACTLY the same effect as walking the acid around the pool AND can cause damage to pool surfaces. When you add acid you convert bicarbonate (TA) into carbonic acid. This action lowers both pH and TA. Carbonic acid is basically CO2 dissolved in water. If you let the CO2 gas off the pH will rise (since the amount of carbonic ACID) in the water is lessened) and the TA will stay where it is (since we cannot form more bicarbonate).

To lower TA safely without causing damage to pool surfaces:

1. drop the pH to 7.0 and no lower with acid ( use an acid demand test in a good test kit to do this)

2. aerate the water to gas off CO2. (fountains, waterfalls, turning the eyeballs upward in the returns to break the water surface, having a 'splash party' in the pool, or anything else that disturbs the water will work. ) The aeration will cause the pH to rise. When the pH is above 7.4 test the TA. (it won't move much at first but will eventually start to move if it is very high). If the TA is still too high repeat from step 1. When the TA is where you want it you are done.

To sum this up:

The main component of TA is the bicarbonate in the water

The act of adding the acid lowers BOTH the pH and the TA by converting bicarbonate into carbonic acid (basically carbon dioxide dissolved in the water). It lowers pH much faster than it lowers TA

Allowing the carbon dixoide created by lowering the pH to gas out of the water causes the pH to rise again because the amount of carbonic ACID in the water decreases. However the amount of bicarbonate does not increase so neither does the TA.

A rise in blood pH typically leads to a reduction in EEG alpha-RMS, indicating reduced brain activity and relaxation. This decrease in alpha rhythms is associated with a more calm and less alert state.

To be competitive for dentistry at McGill, aim for A* grades in IGCSE subjects like Biology, Chemistry, and Mathematics. For A-levels, strive for AAA grades in subjects such as Chemistry, Biology, and another science or math subject. Additionally, gaining relevant work experience or volunteering in a healthcare setting can strengthen your application.

Bases have a pH > 7.0 BUT this merely describes the concentration of ions. Strong usually describes if all the substance ionizes, not how many ions are present.

EX. NaOH is a strong base, but the pH of a solution of NaOH can be anywhere from 7.1 to 14 depending on how much has been dissolved.

Acidic Soil has a low pH .

Remember the pH scale.

1 ( very acidic) ,, to 7 (neutral) ,, to 14 (very alkaline).

Farmers often put lime on acidic soil in order to remove the acidity.

As per the equation.

2H^+(aq) + Ca(OH)2(s) = Ca^(2+)(aq) + 2H2O(l)

It should be noted that plants prefer acidic conditions, and other prefer more neutral/alkaline conditions.

Acetone (C3H6O) has a pH of 7, which means that the substance, on its own, is neither an acid nor a base. This pH value, which is about the same as pure water, shows that acetone is relatively neutral. The organic compound is also known by the IUPAC name of propanone.

Phosphorus trichloride (PCl3) is a covalent compound and does not have a pH level. pH is a measure of the acidity or alkalinity of a solution and is applicable to aqueous solutions. PCl3 is a liquid compound and not soluble in water, so it does not have a pH value.

It is about pH 1 to 2. The gastric acid in our stomach (mainly consisting of hydrochloric acid, HCl) is at this pH level. The acidic medium is necessary for the digestive enzymes, such as those involved in the digestion of proteins, in gastric juice to work.

It depends on the ingredients, the assisting materials or spices you use. If you add a little vinegar, lemon..it will reduce the pH (tends to acidic). Tomato if added will also reduce pH

About 7.9

el pH es un parametro medido para conocer la calidad del agua,saber si permitira un desarrollo optimo del pez,basado en el nivel de acidez y alcalinidad de la misma, (presencia de carbonatos y bicarbonatos).En pisciculturas se toma 2 o 3 veces al dia y los valores van de 6.5-9.

It is very hard to lower pH in an aquarium. The store with suggest using "PH Down," but it does not work. I have tried it, but the pH just goes back to normal within a day. Using chemicals to lower your pH usually will do more harm than good. It is better to just keep your pH at a constant number.

When fire ants bite, they inject a solution into the skin that is an alkaloid mixture that contains allergenic proteins and toxins. The pH of a bite can range from 6 to higher.

It shouldn't. A pH of 5.5 is much too acid to keep tropical fish. The only fish that will survive at this pH are species that are specifically adapted to very acid water, such as chocolate gouramis and some tetras. If you want to keep tropical fish, you will need to buffer the pH by adding something like oxy blocks to your water.

The pH value of natural clean water is 7 making it neutral, however some contaminated H2O are acidic or alkalinic therfore making its pH value range from 1-6 or 8-12. Lemon juice is acidic and contains slaked lime which has a chemical formula of CaO and is pronounced as Calcium oxide, some other kind of lemon/lime is Ca(OH)2 pronounced as Calcium hydroxide.
