What is the relationship between pH and total alkalinity in water chemistry?

The relationship between pH and total alkalinity in water chemistry is that alkalinity helps to buffer or stabilize the pH level of water. Total alkalinity measures the ability of water to resist changes in pH, so higher alkalinity levels can help maintain a stable pH level in 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. 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 is the relationship between total alkalinity and pH in water quality testing?

Total alkalinity and pH are related in water quality testing because alkalinity acts as a buffer that helps to stabilize pH levels. Higher alkalinity levels in water can help prevent drastic changes in pH, making the water more resistant to fluctuations. This relationship is important in maintaining a stable and healthy aquatic environment.


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?

In some cases, soda ash can be used to raise total alkalinity. Pound for pound, soda ash raises alkalinity 60 percent more than sodium bicarbonate and is cheaper than sodium bicarbonate. The problem with using soda ash to increase alkalinity is it drastically increases pH. This can cause cloudy water and scale formation. Soda ash should only be used to increase total alkalinity if you also need to increase the pH or if only small increases in alkalinity are needed.

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?

Alkalinity is different from basicity, which is directly related to the pH. The higher the pH, the more basic the water.Like acidity, there are different ways to measure and report alkalinity;The first is to titrate the water with acid titrant to the phenolphthalein end point. This is called the phenolphthalein alkalinity. Since phenolphthalein changes color at pH~8.3, this corresponds to a pH where all the CO32- present would be protonated.Second, acid titration to a methyl orange end point, pH~4.3, further converts the bicarbonate to aqueous carbon dioxide. At this end point, some of the weaker conjugate bases are protonated. The methyl orange end point titration indicates 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.

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.

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.
