What is polyatomic ion give example?
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
What is the meaning of polyatomic ion?
The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom.
Which are the polyatomic ion?
Because these ions contain more than one atom, they are called polyatomic ions. Polyatomic ions have characteristic formulas, names, and charges that should be memorized. For example, NO3− is the nitrate ion; it has one nitrogen atom and three oxygen atoms and an overall 1− charge….Polyatomic Ions.
| Name | Formula |

| sulfite ion | SO32− |
Is NaCl a ion?
Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion. Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion.
Is Na2SO4 a polyatomic ion?
Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate Na2SO4 .
Is 03 a polyatomic ion?
A polyatomic ion, also known as a molecular ion, is a covalently bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero….Nomenclature of polyatomic anions.
| bromide | As 3− |
|---|---|
| hypobromite | AsO 3− 2 |
| bromite | AsO 3− 3 |
| bromate | AsO 3− 4 |
Which polyatomic ion below has the lowest charge?
Hypochlorite
What is peroxide formula?
H2O2
What is peroxide effect with example?
Example: When propene is made to react with the HBr in the presence of peroxide, then the negative part of the reagent i.e. the bromide ion is attached to the CH2 group of the double bond which consists of the higher number of hydrogen atoms and thus, results in the formation of the n-propyl bromide.
Is peroxide bad for teeth?
This happens because peroxide can cause significant damage to the protective enamel of teeth if used too often or in too-high concentrations. More serious side effects of hydrogen peroxide whitening include inflammation of the teeth roots in the gums.
Does hydrogen peroxide affect pH?
The water used to prepare commercial solutions of H2O2 is generally of very high quality (i.e., deionized, with low acidity), and so does not significantly affect the (real) pH of the product….What is the pH of H2O2 solutions?
| Lowest | Moderate | Highest |
|---|---|---|
| Electronic (etching) | Standard | Metallurgical |
| Pharmaceutical | Dilution | |
| Reagent (laboratory) | ||
| NSF |
Is peroxide basic or acidic?
Hydrogen peroxide is a weak acid, forming hydroperoxide or peroxide salts with many metals.
Is peroxide alkaline or acidic?
Hydrogen peroxide is a weak acid, and it can form hydroperoxide or peroxide salts or derivatives of many metals.
Do peroxide bubbles mean infection?
When you dab hydrogen peroxide on a cut, that white, fizzling foam is actually a sign that that the solution is killing bacteria as well as healthy cells.
Can hydrogen peroxide clean ears?
If your problem isn’t serious, but you do feel like you have too much earwax buildup, you can gently clean the outside of your ears. Just use a washcloth. You also can try putting a few drops of baby oil, hydrogen peroxide, mineral oil, or glycerin in your ear to soften the wax.
