Because water molecules can both split off and accept a proton H+ :
pKw = 14 or Kw = [H3O+]*[OH-] = 10^(-14)
Pure water is neutral, that is, neither acidic nor basic. HOWEVER, it can act as acid as well as base on treating with base and acid respectively. this is said to be aMphoteric chracter of water.
Well... an apple is an acid.
An alkali is a base, so you are combining an acid and a base. This will result in a salt, water and probably a lot of heat being given off as well - stand clear.
Water itself is an acid (as well as a base). However, unless you put another acid in that is the only one present. Pure water is neutral in PH, the scale in which water is determined to be either acidic or alkaline. The dissolved minerals in it, are what determine whether it is acidic or alkaline.
An acid is a proton donor (donates a hydrogen ion), whereas a base accepts the very same proton. For an acid to react there needs to be a base present, i.e. the acid forms a pair with the base, hence an acid-base reaction. Normally, the acid reacts with a water molecule (which as a matter of fact is an ampholyte, meaning water can react either as an acid or a base) that becomes protonated and is then called oxonium.

Strong acids/bases will dissociate to almost 100% in water and their conjugate base/acid will be weak. Weak acid/base will not dissociate well in water and their conjugate base/acid will be strong.

In any means, any acid which does exist is not similar to a base as they are categorized on entirely different behaviour. However, if the word 'alkali' is replaced to the word 'acid' in this question, an alkali is a base which can dissolve well in water, every base is not well soluble in water though.

i believe Starch is a base, or it can be neutral as well.
Well if you read Science is Fun you would know the Answer is obviously Chemical
Well, Vinegar is an acid and Baking Soda is a base and when you mix those two you get a Chemical reaction and that is what happens when you mix any acid and base you get a chemical reaction.
well...hello first here is an acid that starts with v=valeric acid!
Well,i guess the same volume as the base.
