Alkali
Alkali. IF something contains hydroxide ions it is an alkali.
Ammonium hydroxide is an alkali because it gives OH- ions in water and gives a salt on reaction with an acid.
When an alkali (base) and an acid are mixed, they undergo a neutralization reaction where the hydrogen ions from the acid combine with the hydroxide ions from the alkali to form water. This reaction produces a salt as a byproduct. The result is a solution that is closer to neutral pH.
When alkali is added to acid, a neutralization reaction occurs where the hydrogen ions from the acid react with the hydroxide ions from the alkali to form water and a salt. This process results in the solution becoming neutral in terms of pH.
To neutralise a strong acid, you would need a strong alkali (or lots of a weak alkali, but that would be impractical). Potassium hydroxide, sodium hydroxide, lithium hydroxide, calcium hydroxide, calcium hydroxide and magnesium hydroxide would all work.

Ammonium hydroxide is an alkali because it gives OH- ions in water and gives a salt on reaction with an acid.
Sodium hydroxide is an alkali, not an acid.
As with all hydroxides it is an alkali.
Alkaline potassium permanganate solution is a solution of potassium permanganate containing an alkali. The alkali can be sodium hydroxide or potassium hydroxide.

Acids are "H+ donors"; they posses hydrogen ions that (in an aqueous solution) covalently bond with hydroxide ions (from a base in an aqueous solution) to form water. Some examples are: H2S, hydrosulphuric acid HF, hydrofluoric acid HPO4, phosphoric acid HCl, hydrochloric acid ** An Alkali, as you are referring to, is a base. They possess hydroxide ions that (in an aqueous solution) covalently bond with hydrogen ions (from an acid in an aqueous solution) to form water. A few examples: NH4OH, ammonium hydroxide NaOH, sodium hydroxide Mg(OH)2, magnesium hydroxide ** There are a limitless amount of alkali and acid possibilities; you just need to be able to name and balance the one you want correctly.
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
Sodium Hydroxide Solution is a a strong Alkali with a pH reading of 13.
