Can the term hydration be applied to the solvent carbon tetrachloride? Explain your reasoning. If it cannot be used, what term can?
The term hydration usually is reserved for instances in which the solvent, water, becomes attached in one way or another to a molecule. An example is CuSO4*5H2O. Four of the molecules of water are associated with the copper ion and the fifth is associated with the entire crystal. If CCl4 is an adduct, in one form or another, to another molecule or ion, the term solvation (sometimes used for water, also) may be used.
Thanks, what does the *5H20 mean?
Sorry, i don't really understand the answer here.. can the term hydration be applied for CCl4? you said solvation.. yeah im confused.
The term "hydration" specifically refers to the process of adding water molecules to a substance, resulting in the formation of a hydrated compound. It involves the interaction of water molecules with a solute in a solvent.
In the case of carbon tetrachloride (CCl4), it is a non-polar solvent that does not have the capability to form hydrogen bonds with water molecules. This lack of interaction makes it unsuitable for the process of hydration.
Instead, for solvents like carbon tetrachloride that do not readily interact with water, the term "dissolution" is more appropriate. Dissolution refers to the process of solute particles being dispersed and surrounded by solvent particles, leading to the formation of a homogeneous solution. Hence, we can say that carbon tetrachloride can dissolve certain solutes, but it cannot undergo hydration.
