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.
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.
Hydrogen ions are H+Hydroxide ions are OH-neutrons are written n and have no chargeelectrons are written e- and have a negative charge.So only hydrogen ions, H+, has a positive charge.
It contains more ammonia molecules because ammonia is only a weak base.
Magnesium hydroxide Mg(OH)2 can be described as a strong base because it completely ionizes into hydroxide ions.
In a solution of pH of 2, there is more hydrogen ions then hydroxide ions because hydroxide ions only form with a pH pf 7 or more.Note: There are comments associated with this question. See the Discuss:What_can_you_say_about_the_amount_of_hydrogen_ions_relative_to_the_amount_of_hydrogen_ions_in_a_solution_that_has_a_pH_of_2to add to the conversation.
such compounds are bases or alkalies.

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.

No. Alkoxide ions are stronger bases than hydroxide ions. The only way of making an alkoxide is by reacting a hihgly reactive metal such as sodium with the corresponding alcohol (react sodium with methanol to produce sodium methoxide). In water sodium methoxide will react to produce sodium hydroxide and methanol.
No. You could only justify yes if you considered that there wrere sodium ions in solution along with very low quantities of OH- ions (sea water is close to neutral). There are also many other ions, such as Cl-, SO42-
Water ionises to a small extent to produce hydrogen ions an hydroxide ions according to the following reversible reaction: H20 <-> H+ + OH- Although, the reaction tends to lean towards the reverse reaction. It is still able to produce sufficient quantity of hydrogen ions and hydroxide ions needed to conduct electricity. Water conducts electricity through the migration of hydrogen and hydroxide ions.
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
