What is the standard reference method for protein determination?
The standard reference method for protein determination is the Kjeldahl method. This method involves digesting the protein sample with concentrated sulfuric acid and then measuring the amount of nitrogen present, which is used to calculate the protein content.
Why is electrometric method of pH determination more accurate than colorometric method?
The electrometric method of pH determination provides a single value dependent on the concentration of hydrogen ions in the aqueous solution being tested. The colorimetric method of pH determination uses acid-base indicators to provide a range of values for a solution's pH, and is therefore less accurate than the electrometric method.
How do you determine phosphate with the molybdenum blue method yes?
The molybdenum blue method for determining phosphates involves reacting phosphates with ammonium molybdate and ascorbic acid in acidic conditions to form a blue complex. The intensity of the blue color is proportional to the concentration of phosphate in the sample, which can be measured spectrophotometrically at a specific wavelength. Calibration curves are typically used to quantify phosphate concentrations based on the absorbance values obtained.
Why mohr method is better than volhard method?
The Mohr method is typically preferred over the Volhard method for chloride titrations because it does not require a silver nitrate standard solution, making it more cost-effective and simpler to execute. Additionally, the Mohr method is more precise as it allows for a direct endpoint determination based on the formation of a specific silver chloride precipitate.
Why tartaric assay method falls under alkalimetric direct titration method?
The tartaric assay method falls under the alkalimetric direct titration method because it involves the direct titration of tartaric acid with a standardized alkali solution to determine its concentration. The method is based on the neutralization reaction between the tartaric acid and the alkali, which allows for the quantitative determination of the tartaric acid content present in the sample.
What is fiske subbaRow procedure?
It's method of determining the inorganic phosphate content in urine or blood, etc. It is a colorimetric assay.
What is fiske-subbaRow procedure?
The Fiske-subbaRow procedure is a method used in biochemistry to determine the protein concentration in a sample based on colorimetric analysis. It involves reacting protein samples with a reagent containing copper ions, forming a colored complex that can be measured spectrophotometrically to estimate protein concentration. The method is named after the scientists who developed it: Oliver H. Lowry, Nathan J. Rosebrough, Lewis A. Farr, and Rose E. Randall.
What is Nelson method?
its a method for determination of reducing sugars
How is phosphorus produced?
Phosphorus is primarily produced from phosphate rock, a naturally occurring mineral. The process involves mining the phosphate rock, then processing it through chemical reactions to produce elemental phosphorus or various phosphorus-containing compounds. The most common method for phosphorus production is the thermal process, which involves heating the phosphate rock with coke in an electric furnace.
What is the standard reference method for protein determination?
The standard reference method for protein determination is the Kjeldahl method. This method involves digesting the protein sample with concentrated sulfuric acid and then measuring the amount of nitrogen present, which is used to calculate the protein content.
How do you test for hemoglobin?
there are many methods to check the Hb such as Sahli's method cyanmet method specific gravity method etc.
Why is electrometric method of pH determination more accurate than colorometric method?
The electrometric method of pH determination provides a single value dependent on the concentration of hydrogen ions in the aqueous solution being tested. The colorimetric method of pH determination uses acid-base indicators to provide a range of values for a solution's pH, and is therefore less accurate than the electrometric method.
What is the least desirable method of range determination?
visual range estimation
Titan yellow method is used for?
titan yellow used determination of magnesium in serum
What has the author Ramendra Shanker written?
Ramendra Shanker has written: 'A new method for the estimation of dibutyl phosphate (DBP)' -- subject(s): Extraction (Chemistry), Iodine, Tributyl phosphate
What are the methods for the determination of rate of reaction?
In this method we determine the rate of reaction physically.in this method we put the sample in machine and thus we determine the reaction rate.it is very easy method.
Equation for PO4 3- test in water?
To test for the presence of phosphate (PO4 3-) in water, you can use the molybdenum blue method. This method involves adding ammonium molybdate followed by ascorbic acid and sulfuric acid to the sample, which forms a blue complex in the presence of phosphate ions. The intensity of the blue color is proportional to the phosphate concentration in the water sample.
