Many ionic compounds do NOT dissolve in water- such as calcium carbonate. The majority do and that is because the solvation of the ions is energetically favourable in those compounds.
Water is a polar molecule due to its "bent" geometrical construction.

O
/ \
H H
+ +
This construction allows it when ions bump into it to drag different things off. So if NaCl were to bump into this the Na would be attracted to the negative side whereas the Cl would be attracted to the positive side splitting the molecule and causing it to dissolve into the water.
ionic bonding
most ionic compounds will dissolve in water to form ions in solution.
ionic compounds split into individual ions were as covalent compounds dissolves and is surrounded by water molecules
ionic However, it should be noted that not all ionic compounds are water soluble.
Solublity of the ionic compounds vastly vary from one to another. For example, sodium chloride dissolves very well in water, but barium chloride is almost insoluble.
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.

I classify that as an overstatement. It is true that a great many ionic compounds are highly soluble in water, but not all of them.

Ionic compounds are easily dissolved.
because it is a polar molecule
Yes. Water is known as a very good solvent mostly because of its ionic structure. Mostly water dissolves ionic compounds because of the like dissolves like.
Water does not have a pH of 14. By convention water has a pH of 7. Water dissolves ionic compounds because it is a polar liquid.
ionic However, it should be noted that not all ionic compounds are water soluble.
The general rule for solvation is like dissolves like. Water is a very polar molecule. Thus, water best dissolves polar substances, including ionic and polar covalent substances.
