The water molecules surround the negative ions and positive ions and pull them away into the solution. This process is called dissociation
This solution is called water solution or aqueous solution.
Aqueous titration: the ion to be titrated is in an aqueous solution Nonaqueous titration: the ion to be titrated is in an nonaqueous solution
, the alkali metals are powerful reducing agents. Lithium in aqueous solution is as strong a reducing agent as Caesium. This is probably due to high hydration energy of small lithium ion, which compensates for high ionisation energy. The hydration energy of alkali metal ions follows the order: Li+ > Na+ > K+ > Rb+ > Cs+ . Due to extensive hydration, Li+ ion has the highest hydration energy, as a result of which reduction potential of Li is higher than other alkali metals. Thus most powerful reducing agent in solution is lithium.
By observing the [H+] ion concentration and [OH-] concentration in the aqueous solution. If the [H+] ion concentration is higher that the [OH-] ion concentration, it is acidic. Vice Versa for basic.

The formula for Hydronium Ion is H30+. Hydronium Ion is an Aqueous Solution and is also considered as a bare nucleus.
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
This procedure creates an aqueous solution of sodium chloride.
When an acid is placed in water, the hydronium ion (H3O^+) is formed.
Heat of hydration or enthalpy of hydration of ions corresponds to the heat that is released by hydration of one mole of ions at a constant pressure. The more the ion is hydrated, the more heat is released. Degree of hydration depends on the size and charge of ion. The smaller the ion and the greater its charge, it will be the more hydrated.
