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.
What else can I help you with?
Is ammonium molybdate a green chemical?
Ammonium molybdate is not considered a green chemical. It is a chemical compound that is commonly used as a catalyst, reagent, or analytical reagent. However, it has been classified as harmful to the environment and aquatic life, and therefore proper precautions should be taken when handling and disposing of it.
What is the name of Na2MoO4.2H2O?
Sodium Molybdate Dihydrate
Can you prepare ammonia using calcium oxide and ammonium chloride?
Yes. Ammonium salts such as ammonium chloride will react with a strong base to yield ammonia.
What are the two ways to prepare ammonium sulphate?
The two common ways to prepare ammonium sulphate are neutralizing ammonia gas with sulfuric acid or reacting ammonium hydroxide with sulfuric acid. In the first method, ammonia gas is bubbled through sulfuric acid to form ammonium sulphate. In the second method, ammonium hydroxide is slowly added to sulfuric acid to produce ammonium sulphate.
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.
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.
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.
What colour is the precipitate sodium phosphate and ammonium molybdate form?
The precipitate formed from sodium phosphate and ammonium molybdate is yellow.
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.
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.
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.
Is ammonium molybdate an acid or base?
Methane can be protonated by superacids to the carbonium ion: H+ + CH4 -> [CH5]+ So methane is a Lewis base but, like helium, it is an exceedingly feeble proton abstractor. and They can lose a proton, but their tendency to lose a proton is so small that the term acid would not normally be applied to them.
Is ammonium molybdate a green chemical?
Ammonium molybdate is not considered a green chemical. It is a chemical compound that is commonly used as a catalyst, reagent, or analytical reagent. However, it has been classified as harmful to the environment and aquatic life, and therefore proper precautions should be taken when handling and disposing of it.
What is molybdate test?
molybdate test is a test to detect the presence of phosphate at your solution and the appearance at the lab is purple pink as the phosphate is containing lipids and lipids will react with molybdate test to give pink color. Hope this answer you
What is the name of Na2MoO4.2H2O?
Sodium Molybdate Dihydrate
How would you prepare a sample of pure dry ammonium nitrate?
To prepare a sample of pure dry ammonium nitrate, dissolve ammonium nitrate in water to form a saturated solution, then allow the solution to cool and crystallize. Filter and dry the resulting crystals to obtain pure dry ammonium nitrate.
