Completely pure water contains only the ions H+ and OH-.
The first answerer had it right for the most part (Hydrogen ions do not exist by themselves in water, but rather as Hydronium ions, or H3O+)
Water goes through the reversible process of self-ionization:
2 H2O <---> H3O+ + OH-
This is why water has a neutral pH; water has equal amounts of Hydroxide and Hydronium ions, unless an acid or base is added to shift the equilibrium.
What else can I help you with?
Does a solution of ammonia contain mostly ammonia molecules or mostly ammonium ions and hydroxide ions?
A solution of ammonia primarily contains ammonium ions and hydroxide ions. When ammonia dissolves in water, it reacts with water to form ammonium ions (NH4+) and hydroxide ions (OH-), rather than remaining as ammonia molecules (NH3).
What characterizes an Arrhenius base?
It Produces a hydroxide ion
Distilled water is about the only completely neutral solution What is its pH?
The pH of distilled water is around 7, which is considered neutral. This is because distilled water contains equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-), resulting in a balanced pH.
When dissolved in water an arrhenius base yields?
When dissolved in water, an Arrhenius base yields hydroxide ions (OH⁻) as the only negative ions in solution. This is because Arrhenius bases are substances that increase the concentration of hydroxide ions in aqueous solutions.
Do bases dissociate in water to release hydrogen ions and a negative ion other than hydroxide?
Bases can dissociate in water to release ions other than hydroxide. For example, sodamide (NaNH2) releases sodium cations and anionic amide ions (NH2-). Only salts containing hydroxide dissociate to release hydroxide ions (i.e. NaOH). However, the released ion can then react with water to form hydroxide ions. In the case of sodamide, the amide ion reacts with water to produce ammonia and hydroxide ions. Note that the hydroxide is not formed directly by dissociation of the salt, but in a subsequent acid-base reaction.

A solution of ammonia primarily contains ammonium ions and hydroxide ions. When ammonia dissolves in water, it reacts with water to form ammonium ions (NH4+) and hydroxide ions (OH-), rather than remaining as ammonia molecules (NH3).
A compound that dissolves in water to give hydroxide ions as the only negeative ions are what?
such compounds are bases or alkalies.
Is zinc hydroxide is soluble in ammonium hydroxide?
No, zinc hydroxide is not soluble in ammonium hydroxide. Zinc hydroxide is a sparingly soluble compound, meaning it will only dissolve to a very small extent in water. Ammonium hydroxide is not a strong enough solvent to significantly increase the solubility of zinc hydroxide.

In its purest form does water conducts electricity?
Pure water does conduct electricity, but only to a small extent. It contains very low levels of hydrogen ions and hydroxide ions. Try touching power lines with a wet stick and see if you get electrocuted! It's the water, not the wood, that does the damage.
Which base is a weak electrolyte A. sodium hydroxide B. potassium hydroxide C. calcium hydroxide D. ammonia?
D. Ammonia is a weak electrolyte because it only partially ionizes in water to form ammonium ions and hydroxide ions, resulting in a low concentration of ions in solution compared to strong electrolytes like sodium hydroxide, potassium hydroxide, and calcium hydroxide.
Does pure water contain only H2O molecules?
Pure water also contains a small amount of H+ and OH- ions due to self-ionization. This process involves the transfer of a proton from one water molecule to another, resulting in the formation of hydronium (H3O+) and hydroxide (OH-) ions.
Why is ammonium hydroxide conductive?
Ammonium hydroxide is conductive because it dissociates into ammonium ions (NH4+) and hydroxide ions (OH-) in water. These ions are free to move and carry electric charge, allowing the solution to conduct electricity.
Why Is Copper Hydroxide a weak base?
Copper hydroxide is considered a weak base because it only partially ionizes in water to release hydroxide ions. This results in a lower concentration of hydroxide ions in solution compared to strong bases. As a result, copper hydroxide has a lower ability to accept protons and is classified as a weak base.
