Protons (H+, responsible for the acidic behaviour) want to stay near to an anion (the negative part of the acid, eg. Cl-) or (only when present) stick to the partially negative side of a water molecule (the O-side in polar water molecules)
Example:
HCl + H2O --> Cl- + H+OH2

If an acid does not show acidic behavior in the absence of water, the definition of acidity under consideration is one that requires positive hydrogen ions and the substance concerned can not produce any such ions in the absence of water, sometimes because they do not contain any hydrogen. This is the common definition of acidity in aqueous solutions. Acidity as defined by G. N. Lewis by loss or gain of electron pairs, however, can occur in the absence of water.
The correct order of acidic strength is as follows: strong acids > weak acids > organic acids. Strong acids completely dissociate in water to release H+ ions, making them the most acidic. Weak acids partially dissociate in water, while organic acids generally have a carboxylic acid group and are typically weaker acids.
The definition of an acid is the formation of the hydronium ion, H3O+. This comes about ONLY in the presence of water, H2O, where H2O + H+ ==> H3O+. It is a phenomenon of aqueous solutions, so water must be present.
Acidic oxides form (oxy)acids with water: eg. SO2 + H2O --> H2SO3
Practically, coconut water shows acidic behaviour, as the solution undergoes oxidation to produce ethanoic acid. Otherwise, coconut water is neutral.
Some salts dissolved in water have an acidic pH.
To make water acidic, one can add an acid such as vinegar or lemon juice. Acids release hydrogen ions when dissolved in water, lowering the pH level and making the water more acidic.
Acidic oxides react with water to form acids, while basic oxides react with water to form bases. Acidic oxides have a higher concentration of oxygen ions, leading to a more acidic solution when dissolved in water. Basic oxides have a higher concentration of metal ions, resulting in a more basic solution when dissolved in water.
Because water is slightly acidic from all the acids in the air!
Yes, both sulfur oxides are acidic: with water the give sulfurous (weak -) and sulfuric (strong -) acids
Oxides can be classified into acidic, basic, amphoteric, or neutral based on their chemical reactivity with water. Acidic oxides react with water to form acids, basic oxides react to form bases, amphoteric oxides can act as both acids and bases, while neutral oxides do not react with water to form either acids or bases.
As the acids after mixing with the water get ionize, and the resulting ions are held by the water molecules separately. When the water molecule get evaporate sometimes they take away these acidic ions with them and thus the concentration of acids get lower in the sample.
