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.

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 phosphate an anion or cation?
Phosphate is a triply charged polyatomic anion.
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?
When KCl is dissolved in water, it dissociates into K+ ions and Cl- ions. These ions are responsible for conducting electricity in the solution.
How H2O different from H2O2?
H2O is the chemical formula for water, a molecule composed of two hydrogen atoms and one oxygen atom. H2O2 is the chemical formula for hydrogen peroxide, a molecule made of two hydrogen atoms and two oxygen atoms. Hydrogen peroxide is a stronger oxidizing agent compared to water and is often used as a disinfectant.
What is NAHCO3 in H2O?
NAHCO3 in H2O refers to the chemical reaction when sodium bicarbonate (NAHCO3) is added to water (H2O). When added to water, sodium bicarbonate dissociates into sodium ions (Na+) and bicarbonate ions (HCO3-), resulting in a solution commonly known as bicarbonate of soda.
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?
PO4 is an anion. It has a negative charge of 3-.
Which type of chemical reaction occurs in Ca plus Cl2--- CaCl2?
The chemical reaction that occurs in Ca + Cl2 to form CaCl2 is a combination reaction, also known as a synthesis reaction. In this type of reaction, two or more reactants combine to form a single product.
Is phosphate an anion or cation?
Phosphate is a triply charged polyatomic anion.
Is Cl- a cation or anion?
Cl -As this is a negatively charged ion it is a anion.
What are the ions of water and what are their charges?
H2O ionized to.... H + ( a proton, a stripped of it's electron hydrogen atom and a cation. Positive charge ) OH - ( hydroxide polyatomic ion and an anion. Negatively charged. )
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 carbon a cation or anion?
anion
