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?
# The pH will determine if the bacteria will have a particular charge. If the chromophore is a positive ion like the methylene blue in the equation shown in the reading, the stain is considered a basic stain; if it is a negative ion, it is an acidic stain. Most bacteria are stained when a basic stain permeates the cell wall and adheres by weak ionic bonds to the negative charges of the bacterial cell.
Why does silver nitrate test provide negative result on the presence of a chloride ion?
Due to presence of chloride ion
How can you test for hydroxide ion?
Turns litmus paper blue
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 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?

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..
What is a positive test for an ion?

What is the number of protons in Fe 3?
This ion is yellowish brown color in water. Ion contains 26 protons.
