Water behaves as a base with the hydrogen halides due to the fact that when dissolved in water the hydrogen halide dissociates into its ions, and the water molecule acts as a proton acceptor (base) when it combines with the hydrogen ion to form hydronium (H3O+), and the halogen forms its negative halide ion. The following example shows the reaction between hydrogen chloride and water.
HCl + H2O --> H+ + Cl- + H2O --> H3O+ + Cl−
Alkyl halides undergo elimination reactions, such as E2 and E1, to form alkenes and hydrogen halides. This occurs in the presence of a base or nucleophile due to the tendency of the halide to leave, resulting in the formation of a double bond. The presence of a strong base favors elimination over substitution reactions.
A base is a substance that contains hydroxide ions (OH-) which can accept protons from water, resulting in the formation of hydroxide ions and free hydrogen ions (H+). This is why a base is known to form hydrogen ions in water.
When a base accepts a hydrogen ion from an acid, it forms a water molecule. This process is known as neutralization, where the base and acid combine to produce water and a salt.
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
No, hydrochloric acid is an acid, not a base. It is a strong acid that dissociates in water to release hydrogen ions.

Ammonia behaves as a Lewis base as it can donate a lone pair of electrons.It is a compound of nitrogen and hydrogen (NH3).It is also a gas at room temperature, and an alkali in water, in which it is extremely soluble. It is an important starter chemical for the agrichemicals industry.

Electrolytes that release ions that combine with hydrogen atoms are called bases.

Neither, it is water a neutral substance.

The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
Yes it does. pH is defined as the -log of the concentration of hydrogen ions in a solution, or -log[H+]. As you add water to an acid, you are diluting it, thus lowering the concentration of H+. Putting a lower value in for [H+] in the equation -log[H+] will give you a great value than you originally had. This means the pH has increased, making the solution more basic.
When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.
No, hydrochloric acid is an acid, not a base. It is a strong acid that dissociates in water to release hydrogen ions.
Yes, it can. When an oxide behaves as acid and base, it is neutral. Examples: Aluminum oxide and the most common: water
