Neither, it's a salt.
No. Lewis acids are electron acceptors, forming adducts.
The Lewis base donates one or more pairs of electrons to the Lewis acid in order to form a compound with one or more dative bonds.
A Lewis acid.
yes
Stannic chloride is a better Lewis acid
Usually nothing happens as silica is a very nonreactive substance. However, hydrofluoric acid will react with glass in the following manner. 4HF + SiO2 --> SiF4 + 2H2O The SiF4 escapes as a gas.
No it is not a Lewis Acid, H+ is!
Neither, it's a salt.
I think it is acid, because there is a question that asks the acid site of SO3.
A Lewis acid accepts electron pairs.
Sf6 acts as an lewis acid............
A Lewis acid accepts electron pairs.
Lewis acid is an electron pair acceptor.
Aluminium trichloride is a salt. It is considered an acid after Lewis theory.
Yes, SO2 is a Lewis acid when combined with OH-
Mg2+ is (theoretically speaking) a Lewis acid, but I don't know how strong.
