Question
A solute is considered a weak electrolyte if ____.
Answer
A solute is considered a weak electrolyte if it ionizes or hydrolyzes incompletely in aqueous solution, and only some of the solute is dissolved into its ionic constituents.
Note: Examples include Hg2I2 (Ksp = 4.5 × 10–29), acetic acid and other weak acids, and ammonia and other weak bases.
Note: Examples of strong electrolytes include certain ionic compounds, such as NaCl and KI, and molecular compounds with highly polar covalent bonds that dissociate into ions when dissolved, such as HCl in water. An example of solvation of such compounds is shown in Figure 4.10.

Formula unit represents ____.
____ represents the empirical formula of an ionic compound, since they do not form true molecules, rather a coordinated lattice.
____ weight is the term used for ionic compounds "molecular" weight as no molecule actually exists, its just a lattice structure.
____ compounds form from elements of similar electronegativity.
Atomic weight is ____.
____ is a weighted average of the masses of the naturally occurring isotopes of an element, not their weights.
