H2O is written without a symbol for charge because the molecule has no charge. A water molecule is neutral.
Ions will always have a charge.
If H2O were to dissociate to H+ and OH-, then you would have two ions (note the charges). H2O ---> H+ + OH-
It is worth mentioning that this reaction doesn't really happen, even if you see it written a lot. There is a complex structure to water and we usually acknowledge that by saying the "solvated proton" becomes a hydronium molecule and the actual reaction is H2O + H2O ---> H3O + OH- .
In fact, it is a dynamic process and the proton does not stay with one water molecule and may exist in a state associated with several molecules. But, that takes the answer too far off track.

∙ 16y agoHydroxide (OH-) contains both an atom of oxygen (O) and hydrogen (H). Many ions are from only ONE atom or element, but since OH- contains two separate elements, it is polyatomic.

Is phosphate an anion or cation?
Phosphate is a triply charged polyatomic anion.
CO2 H2O H2CO3 H3O HCO3?
* CO2 is the chemical formula of carbon dioxide.* H2O is the chemical formula of water.* H2CO3 is the chemical formula of carbonic acid.* HCO3- is the chemical formula of the anion bicarbonate (the correct name is hydrogen carbonate)* H3O+ is the chemical formula of the cation hydronium
Is chloride a cation or an anion?
chloride is an anion.
Why is CaSO4 less soluble in water than NaCl?
The ion-ion bond in CaSO4 is stronger than in NaCl because of the higher charges on the cation and anion. Be careful in making this argument. The ion-dipole forces of Ca2+ -H2O and SO42- - H2O might actually be stronger than that of Na+ -H2O and Cl- -H2O due to the high charges on Ca2+ and SO42- . However the strengths of the ions-dipole interactions do not match (or exceed) the strength of the Ca2+ -SO42- ionic bond.
What is the anion of chlorine?
The anion of chlorine is chloride (Cl-).
What ions are produced when KCl dissolved in H2O?
The cation,K +and the anion,Cl -
How H2O different from H2O2?
H2O is water which is formed from a covalent bond between hydrogen and oxygen. H2O2 is hydrogen peroxide which is formed from an ionic bond between the hydrogen H+ cation and the peroxide O2- anion.
What is NAHCO3 in H2O?
Na is sodium which has a charge of +1. This is your cation HCO3 is Hydrogen Carbonate which has a charge or -1. This is your anion. Thus your final answer would be Sodium Bicarbonate
What is the name of this ClO?
'Hypochlorite' anion (from bleach) also called 'active chlorine': OCl- + Cl- + H2O --> 'Cl2' + 2 OH- (slow)
When sodium chloride and hydrochloric acid react then why sodium hydroxide do not formed?
The reaction is: NaOH + HCl = NaCl + H2O HCl and NaCl cannot react, the anion is the same.
Is PO4 a cation or an anion?
polyatomic anion
Which type of chemical reaction occurs in Ca plus Cl2--- CaCl2?
There is no equation for reacting CaCl2 and H2O. This is because nothing happens when these two chemicals combine because there is no reaction. If one was to add CaCl2 to H2O, he would end up with wet calcium chloride.
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
Is carbon a cation or anion?
anion
Is a protein a cation or anion?
Anion
