Difference Between p Alkalinity and m Alkalinity

The main difference between p Alkalinity and m Alkalinity is that p Alkalinity is the measurement of alkalinity given by hydroxide ions and half of the carbonate alkalinity whereas m alkalinity is the measurement of alkalinity given by hydroxide ions and total carbonate alkalinity.

What is P alkalinity?

P-alkalinity (also known as phenolphthalein alkalinity) – is determined by titration with acid to pH 8.3. It measures the amount of carbonate alkalinity, hydroxyl alkalinity, and a part of bicarbonate alkalinity in a sample. ... If P-alkalinity is zero, then the water is free of hydroxide and carbonate alkalinity.

What is M alkalinity in boiler water?

In boiler water, treatment specialists must maintain M (or T) alkalinity below a maximum level prescribed by the boiler's manufacturer to help prevent foaming and carryover. ... The higher the pH, the more alkalinity is present in the carbonate species, which can react with calcium in the water to form scale.

What is the purpose of the P alkalinity test of boiler water?

P-ALKALINITY:- THIS TEST IS CARRIED TO FIND OUT THE PRESENCE OF ALKALINE IN BOILER WATER. BOILER WATER SHOULD BE ALKALINE TO SAVE IT FROM CORROSION. ALKALINITY IS DUE TO HYDROXIDE AND CARBONATES AND HYDROXIDE. P ALKALINITY IS USED TO FIND OUT ALKALINITY DUE TO CARBONATES.

What is alkalinity and its types?

Alkalinity is a measurement of dissolved alkaline substances in water (higher than 7.0 pH). It tells us the water's ability to neutralize acid. There are three primary types: Bicarbonate. Carbonate.

What is the normal range of alkalinity?

The Normal amounts of Alkalinity:

Fresh water amounts range from 20-200 mg/l. Seawater amounts on average are 100-125 mg/l.

Does alkalinity affect pH?

Water pH measures the amount of hydrogen (acid ions) in the water, whereas water alkalinity is a measure of the carbonate and bicarbonate levels in water. ... The higher the alkalinity of the water, the more lime it contains and therefore, the more rapidly the water can cause the growing medium pH to rise.

What is the difference between phenolphthalein alkalinity and total alkalinity?

Phenolphthalein alkalinity is determined by titration to a pH of 8.3 and indicates the total hydroxide and half the carbonate present. Total alkalinity is determined by titration to a pH of 5.1, 4.8, 4.5 or 3.7 depending upon the amount of carbon dioxide present.

How do you calculate alkalinity?

Alkalinity as CaCO3 = 0.0097 Eq/L x 50 g/Eq = 0.485 g/L = 485 mg/L. Thus, if the solution density is close or equal to 1, then ppm = mg/L.

What is water alkalinity test?

Alkalinity is a measure of the capacity of water to neutralize acids (see pH description). ... Total alkalinity is measured by measuring the amount of acid (e.g., sulfuric acid) needed to bring the sample to a pH of 4.2.

What does alkalinity mean water?

Alkalinity is the water's capacity to resist changes in pH that would make the water more acidic. ... The pH of the buffered solution would change when the buffering capacity of the solution is overloaded. Alkalinity refers to the capability of water to neutralize acid.

What is hydrate alkalinity?

ALKALINITY (HYDRATE) Hydrate alkalinity is a component of total alkalinity. Boiler operators must maintain relatively high hydrate alkalinity levels when phosphate cycle treatments are used to ensure the formation of softer, more easily removable deposits.
