If it produces hydroxide ions (OH-) when dissolved in water, it is considered a base. Examples would be sodium hydroxide (NaOH), potassium hydroxide (KOH), and even ammonia (NH3) because
NH3 + H2O ==> NH4+ + OH-
Water molecules form hydrogen bonds with each other. These bonds form between the hydrogen atom of one water molecule and the oxygen atom of another water molecule. Hydrogen bonding is responsible for the unique properties of water, such as its high boiling point, surface tension, and the ability to dissolve many substances.
No, hydrogen ions can combine with other molecules or ions besides water. For example, hydrogen ions can combine with hydroxide ions to form water, or they can bond with substances like ammonia or carbonates.
The compound hydrogen chloride, with formula HCl.
Water polarity allows it to form hydrogen bonds. These bonds are formed between the slightly positive hydrogen atom of one water molecule and the slightly negative oxygen atom of another water molecule. The presence of hydrogen bonding gives water its unique properties, such as high surface tension and the ability to dissolve many substances.
Water's strong polarity (due to its unique combination of hydrogen and oxygen and the electrons included therein) is responsible for most of water's properties. It allows water to dissolve most ionic substances, it causes surface tension, it explains why water expands when it freezes (most substances don't), and it explains why snowflakes have six sides.
In addition to water, other substances that can form hydrogen bonds include ammonia, alcohols, and organic compounds like DNA and proteins.
Chemical compounds called acids will do this.

No, hydrogen fluoride anhydrous is the anhydrous (without water) form of hydrogen fluoride, while hydrofluoric acid is the aqueous (dissolved in water) form of the compound. Both substances contain the HF molecule but differ in their physical state.

Heat energy is released when water condenses as hydrogen bonds form. This is because the molecules are coming closer together, releasing energy that was used to keep them apart in the vapor phase.
Hydrogen and oxygen are both elements. They are found in the periodic table as pure individual substances. When they chemically combine, they form the compound water (H2O).
Acids are substances which, when dissolved in water, dissociate to form hydrogen ions (H+ ions). Since barium chloride does not contain hydrogen ions, it is not an acid.
Hydrogen ions mixed with water(H2O) atoms to form positively charged hydronium(H3O+). The other product is the cation of acid.
When hydrogen and oxygen combine to form water, water is a product of the reaction.
No, not all substances dissolve in water to form a solution. Cooking oil is a good example, if you mix with water it will remain separated and float to the top - it is less dense. Water would have to break almost all its intermolecular hydrogen bonds in order to accomodate it (which of course it doesn't), and therefore it does not form a solution. Solubility depends on what you are adding to the water. If you are adding an alcohol for example, it has O-H bonds which will readily form hydrogen bonds with the water molecules, and so dissolves. Water is also a polar solvent, so ionic substances will also tend to dissolve in it. Hope that helps!
