What is the chemical formula for barium permanganate?
A permanganate anion has a single negative charge, while a barium cation has two positive charges. Therefore, the formula for anhydrous barium permanganate is Ba(MnO4)2.
Is Cl- a cation or anion?
Cl -As this is a negatively charged ion it is a anion.
Is carbon a cation or anion?
anion
Is br a anion or cation?
Bromine forms the Br- anion
Is po43- a polyatomic anion or cation?
Phosphate (PO43-) is a polyatomic anion. The way to tell this is to look at the charge - an anion has a negative charge and a cation has a positive charge.
What is the chemical formula of a permanganate anion?
This doesn't really make sense. MnO4− is the symbol for a permanganate ion, however it is not a formula.
What is the formula for permanganate and ammonium?
Permanganate refers to the permanganate anion (MnO4-), and ammonium refers to the ammonium cation (NH4+).
What is the hybridisation of manganese in Potassium permanganate?
Potassium Permanganate (KMnO4) is a tetrehedral anion.
What is the permanganate ion composed of?
MnO4- is the chemical formula for permanganate. The charge is generally -1.
What is the chemical formula for barium permanganate?
A permanganate anion has a single negative charge, while a barium cation has two positive charges. Therefore, the formula for anhydrous barium permanganate is Ba(MnO4)2.
How many atoms of oxygen are in the formula MnO2?
1 K ( Potassium ) 1 Mn (Manganese) 4 O ( Oxygen ) This is an ionic compound consisting of a +1 potassium cation and a -1 permanganate (polyatomic) anion (MnO4) When this dissociates in water, the K separates from the permanganate, but the permanganate stays together as MnO4
Is potassium permanganate ionic or molecular compound?
It is an ionic molecule because it is composed of a cation and anion.
Is PO4 a cation or an anion?
polyatomic anion
How do you test the presence of potassium bromate in flour?
Presumably, one could dissolve a certain amount of flour in water, then look for the bromate anion in the water. Bromate anion research methods are good to ppb levels.
Is Cl- a cation or anion?
Cl -As this is a negatively charged ion it is a anion.
Is phosphate an anion or cation?
Phosphate is a triply charged polyatomic anion.
Which describes an anion?
An anion is an ion with a negative charge - so SO42- is an anion
