What is ammonium molybdate test?
The ammonium molybdate test is a qualitative analytical test used to detect the presence of phosphate ions in a sample. It involves adding ammonium molybdate reagent to the sample, resulting in the formation of a yellow precipitate if phosphate ions are present. The intensity of the yellow color can provide an indication of the concentration of phosphate ions in the sample.
Why Ammonium molybdate is used in test for phosphorus?
Ammonium molybdate is used in the test for phosphorus because it forms a yellow complex with phosphorus, which allows for the colorimetric determination of phosphorus levels. This reaction is commonly used in spectrophotometric methods to quantify phosphorus in various samples.
How do you make 0.1m of ammonium molybdate?
To make 0.1m of ammonium molybdate, you would need to dissolve the appropriate amount of ammonium molybdate powder in a specific volume of water to achieve a molarity of 0.1M. The molecular weight of ammonium molybdate is 196.00 g/mol, so for 0.1M solution, you would dissolve 19.6g of ammonium molybdate in water to make a final volume of 1 liter.
Is ammonium molybdate a base?
No, ammonium molybdate is not a base. It is a chemical compound commonly used in analytical chemistry for the detection of phosphates and silicates.
How do you prepare 0.5M ammonium molybdate?
Ammonium molybdate is (NH4)2MoO4. Its molar mass is 148g/mol. A 0.5M solution will have half a mole per liter of water. Half a mole of ammonium molybdate is 74g, so you would measure out 74g of it, and dissolve it in a liter of water.

The intensity of the yellow color can provide an indication of the concentration of phosphate ions in the sample.
Would a hydrolysate of casein give a positive test with ammonium molybdate?
A hydrolysate of casein would likely not give a positive test with ammonium molybdate, as casein hydrolysate molecules are broken down into smaller peptides and amino acids, which may not have the specific chemical groups necessary for the molybdate test to detect. The test with ammonium molybdate typically reacts with phosphorus compounds to form a colored compound, and casein hydrolysate may not contain sufficient phosphorus for a positive result.

What is the name of Na2MoO4.2H2O?
Sodium Molybdate Dihydrate
How would you test a urine sample for phosphate ions?
To test a urine sample for phosphate ions, you can use a phosphate test strip or a colorimetric method. The test strip changes color in the presence of phosphate ions, providing a semi-quantitative result. Alternatively, a colorimetric method involves adding reagents that react with phosphate ions to produce a colored solution whose intensity can be measured to quantify phosphate levels in the urine sample.

What is the formula for zinc molybdate?
ZnMoO4
What is the molecular formula for silver molybdate?
Ag2MoO4 is the molecular formula for silver molybdate.Silver molybdate are yellow crystals which are slightly soluble in water.
Is ammonium molybdate a base?
No, ammonium molybdate is not a base. It is a chemical compound commonly used in analytical chemistry for the detection of phosphates and silicates.
What colour is the precipitate sodium phosphate and ammonium molybdate form?
The precipitate formed from sodium phosphate and ammonium molybdate is yellow.
