In BF3, boron has an uncompleted octet where two more electrons can be obtained. Therefore it can act as a Lewis base.
Lewis base gives out a lone pair of electrons.N of NH3 has a lone pair.So it can act as Lewis base.
lone pair enables CO to act as a Lewis base
Copper sulfate (CuSO4) is neither an acid nor a base, but is a salt.
Lewis Acid are able to accept electrons. Boron in Boron Trifluoride only contains 6 electrons, thus making it able to receive 2 more electrons to complete it's octet. Also, Boron is an exception that it is stable with a sixtet, which makes it BF3 a neutral molecule.
it can either be an acid or a base depending on its participation in the reaction. if it accepts H+ then it is a base and if it donates H+ then it is an acid..

Aspirin is acetylsalicylic acid. Consequently, it can act as a Lewis acid. Ammonia is a Lewis base. Therefore, ammonia and aspirin can react to form the ammonium salt of aspirin.

When ammonia is added to water, it acts as a base. This is because according to Lewis Concept of Acids and Bases, a lone pair donor is a base. NH(3) donates its lone pair to H+ ion from water and hence is a base.
Acids or bases change character based on the solution in which they exist. For instance, HCl is a strong acid in water, but is a weak acid when dissolved in glacial acetic acid. This has to do with the proton affinity of the respective acids and bases. So, nitric acid may act as a base when placed in a solvent that has a lower proton affinity, i.e., the nitric acid will accept the proton as a Bronsted-Lowry base. I'm not as familiar with Lewis acids and bases, but Lewis bases donate electron pairs, and Lewis acids accept them. I'm sure there is a circumstance in which nitric acid will donate an electron pair to a Lewis acid.
It is a Lewis base:PCl3 has a lone electron pair in the highest occupied molecular orbital available for donation.( Note: PCl5 is a Lewis acid!)
None of the original base remains in solution.
Yes they are, Bases are also Electron acceptors.
This depends on your definition of an acid. The answer is presumably Hydrogen, because most definitions of acids and bases require compounds to donate H+ ions or produce H+ ions. However, there is an alternative definition of acid put forth by G.N. Lewis (the Lewis structure guy) that says that a molecule is an acid if it is a lone-pair acceptor. According to that definition such things as BF3 would be considered acids.
