How is the Brown ring test performed?
The Brown ring test is performed by adding a small amount of nitric acid to a nitrate solution containing a Fe2+ ion. A brown ring forms at the junction of the two layers if the nitrate ion is present. The test is based on the reaction between Fe2+ and NO+ ions.
What is the chemical formula of bismuth III perchlorate?
The chemical formula of bismuth III perchlorate is Bi(ClO4)3. It consists of one bismuth (Bi) ion and three perchlorate (ClO4-) ions.
The element which is isoelectronic with phosphide ion?
Nitride (of Nitrogen), Arsenide (of Arsenic), Antimonide (of Antimony), Bismuthide (of Bismuth) and Boride (of Boron)
How do you extract bismuth from bismuth nitrate?
A single replacement reaction would most likely be the best method. By adding a metallic element of higher reactivity to the compound the Bismuth will separate from the Nitrate ion and the matallic element of higher reactivity will take its place. The Bismuth Nitrate would have to be in an aqueous solution however.
Methylene blue can be prepared as a basic stain or an acidic stain. How would the pH affect the staining of bacteria?
When methylene blue is prepared as a basic stain, it will have a positive charge and selectively bind to negatively charged components of bacterial cells, such as nucleic acids, enhancing the staining of bacteria. On the other hand, if prepared as an acidic stain, it will have a negative charge and repel bacterial cells, resulting in poor staining of bacteria.
What is the charge on stable ion of bismuth?
Bismuth is considered to be a poor metal having an atomic number of 83. The metal carries a charge of +3 . Bismuth has been in existence since ancient times.

WHAT IS TEST REAGENT USED TO IDENTIFY NITRATE ION?
A common test for nitrate ion is with diphenylamine.
What is a brown ring test for analysis of nitrate anion using formula?
A nitrate test is a chemical test used to determine the presence of nitrate ion in solution. A common nitrate test, known as the brown ring test[1] can be performed by adding iron(II) sulfate to the solution, then slowly adding concentrated sulfuric acid (NOT nitric acid, for obvious reasons) and watching for a brown ring on the test tube, which will indicate the presence of the nitrate ion.[2] Note that the presence of nitrite ions will interfere with this test.[3]The test follows several phases; these have been written as balanced chemical equations: 1: 2 Zn(NO3)2 + 2 H2SO4 → 2 ZnSO4 + 4 HNO3 4 FeSO4 + 2 H2SO4 → 2 Fe2(SO4)3 + H2 These two reactions happen simultaneously. 2: 4 HNO3 → 2 H2O + 3O2 + 2 NO The Nitric Acid decomposes in the intense heat produced by the high concentrate Sulphuric Acid used. 3: 2 Fe2(SO4)3 + 2 H2 + 4 NO → 4 Fe.NO.SO4 + 2 H2SO4 The Fe.NO.SO4 forms a brown ring in the middle of the solution produced by the reaction, making it easy to identify the presence of nitrates in the water.
What is a test for nitrate ions?
A common nitrate test is known as the brown ring test or iron ring test.It can be performed by adding FeSO4 to the solution, then slowly adding concentrated sulfuric acid and watching for a brown ring on the test tube, which will indicate the presence of the nitrate ion.[Fe(H2O)5NO]SO4 forms a brown ring in the middle of the solution produced by the reaction;the 'NO' part of this complex comes from the auto-redox of nitrate NO3- to NO (and O2) by sulfuric acid.Note that the presence of nitrite ions will interfere with this test, reacting directly as 'NO'.Do NOT use nitric acid, since it gives nitrate ion which gives a positive result anyway).
How do you do the ion test for boron?
It fizzes
How are ion pairs formed?
test
What color flame test does the iodide solution give in flame test?
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
What compound is present in the brown ring?
Nitrate ion..
