1. The generic formula for an acid is HA (aq)
ACIDS
In its simplest form, an inorganic acid is defined as a hydrogen salt dissolved in water. By this definition a simple inorganic acid exists in the aqueous state.
The generic formula for an acid is HA (aq)
NOTE: they all have the generic formula H-anion
