Are all ionic substances soluble in water?
Absolutely not. A great many ionic species are INSOLUBLE in water.
Ionic compounds are non-molecular. They consist of a rigid array of positive and negative ions, whose attractive electrostatic interaction persists throughout the ionic lattice. A measure of this ionic interaction can be measured (both experimentally and theoretically) by the lattice enthalpy.
Of course, network covalent solids are also non-molecular, and the individual particles are bound together by strong covalent bonds. You would have a hard time dissolving graphite or silicon dioxide in water.
I am certainly willing to expand on the subject. It depends whether you are in A level or are an undergraduate.

Not all ionic substances are soluble in water. The solubility of an ionic compound depends on the strength of the bonds holding its ions together and the interactions between the ions and water molecules. Generally, compounds with strong ionic bonds or with ions that are highly charged tend to be less soluble in water. Additionally, compounds with large ions or with ions that have a strong affinity for water tend to be more soluble.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
