Phenolphthalein alkalinity measures the hydroxide ion concentration in water, specifically the amount that can be neutralized by strong acids. Total alkalinity, however, measures the water's ability to neutralize acids, including carbonate, bicarbonate, and hydroxide ions. In summary, phenolphthalein alkalinity focuses on the hydroxide ions, while total alkalinity considers a broader range of alkaline substances.

Why double indicator is used during the titration of water to find alkalinity of water sample?
Double indicator (phenolphthalein and methyl orange) is used during the titration of water to find the alkalinity of the water sample because each indicator changes color at different pH ranges. Phenolphthalein changes color in the alkaline pH range, indicating the endpoint of the titration for total alkalinity. Methyl orange changes color in the acidic pH range, aiding in the detection of the endpoint for carbonate alkalinity. Using both indicators helps to accurately determine the different forms of alkalinity present in the water sample.
What does the mean of m alkalinity and p alkalinity in boiler water?
1. M-Alkalinity (also known as Total Alkalinity) measures the amount of carbonate, bicarbonate and hydroxide present in terms of "ppm as calcium carbonate". ( M-Alkalinity measurement is based on a sulphuric acid titration using a Methyl orange indicator that goes from yellow at a pH of 4.5 to orange at pH of 4.4 at the endpoint.) 2. P-Alkalinity measures the amount of carbonate and hydroxyl alkalinity present in terms of "ppm as calcium carbonate". P-alkalinity is measured down to a pH of 8.3. The M-alkalinity is measured down to a pH of 4.3.
Will soda ash raise pool alkalinity?
Yes, soda ash (sodium carbonate) can raise pool alkalinity when added to the water. It is commonly used to increase alkalinity levels in swimming pools, which helps stabilize pH levels and prevent fluctuations.
How can your pool have high total alkalinity and very low pH?
High total alkalinity can act as a buffer and prevent pH from changing. However, if the pH becomes very low due to factors like rainwater, acidic chemicals, or improper maintenance, the alkalinity may not be strong enough to keep the pH balanced. Regular testing and adjusting of both parameters are necessary to maintain proper water balance.
How much baking soda do you use to raise total alkalinity in a 20000 gallon pool?
To raise the total alkalinity in a 20,000 gallon pool, you can typically add 1.5 pounds of baking soda for every 10 parts per million (ppm) increase you desire. Calculate how many ppm you need to raise your alkalinity by, and then use this ratio to determine the amount of baking soda needed for your specific situation.
What is phenolphthalein alkalinity?
Phenolphthalein alkalinity is a measure of the total amount of hydroxide ions, bicarbonate ions, and carbonate ions present in a solution. It is determined by titrating the solution with acid until the pH reaches a specific endpoint indicated by a color change of phenolphthalein indicator.
Why methyl orange alkalinity equal to total alkalinity?
Methyl orange alkalinity represents the hydroxide and carbonate alkalinity in water. Total alkalinity includes hydroxide, carbonate, and bicarbonate alkalinity. When methyl orange turns red in water, it indicates the presence of carbonate and hydroxide ions, which make up the alkalinity, thus making methyl orange alkalinity equal to total alkalinity.
Why the water sample remains colorless or change to pink upon addition of phenolpthalein indiactor in total alkanilty expt?
In a total alkalinity experiment, the water sample may remain colorless or change to pink upon the addition of phenolphthalein indicator based on the pH of the water sample. If the water sample is acidic (pH below 8.3), phenolphthalein will remain colorless. If the water sample is basic (pH above 8.3), phenolphthalein will turn pink due to the presence of hydroxide ions, indicating the total alkalinity of the water.
Why double indicator is used during the titration of water to find alkalinity of water sample?
Double indicator (phenolphthalein and methyl orange) is used during the titration of water to find the alkalinity of the water sample because each indicator changes color at different pH ranges.

Using both indicators helps to accurately determine the different forms of alkalinity present in the water sample.
What causes low total alkalinity?
Improperly sanitized water or excessive rainfall can cause a low total alkalinity level in your pool. Low total alkalinity can cause pool staining, itchy and burning eyes and skin, and corrosion of metal parts in the pool.
What is the difference between total customer value and total customer cost?
The difference between total customer value and total customer cost is__________.
What causes low alkalinity?
Improperly sanitized water or excessive rainfall can cause a low total alkalinity level in your pool. Low total alkalinity can cause pool staining, itchy and burning eyes and skin, and corrosion of metal parts in the pool.
Will chlorine shock raise the TA?
Chlorine will not raise the total alkalinity level in a pool. However, if you are trying to raise the total alkalinity, you can add small amounts of baking soda.
If pool water is clear but surfaces are slippery is this algae?
It could be, but sounds more like hi alkalinity. Check your TA ( total alkalinity ) It should be between 80-120 ppm. You can bring it down using muriatic acid if you need to.
Will adding a flocculant to the pool water lower the Total Alkalinity?
No
What is the difference between the sum and the total?

Is alkalinity dangerous for humans in swimming pools?
Alkalinity is not an actual "chemical", however if you are concerned about increasing the alkalinity in your swimming pool, you are perfectly safe. The chemical that increases "total alkalinity" in a swimming pool, is only baking soda. It wil not harm the human body!
