A Lewis acid accepts an electron pair.
A Lewis acid.
There are three definitions for acids and bases. Arrhenius definition: An acid is a substance that produces hydrogen (H+) ions in water while a base produces hydroxide (OH-) ions. Bronsted-Lowry definition: An acid gives up or donates a proton (H+) to another molecule while a base accepts a proton. Lewis definition: An acid accepts an electron pair in bonding to another molecule/ion while a base donates and electron pair. Note that if a substance meets one of the first two definitions it probably meets the others as well.
A Bronsted-Lowry base is a substance that accepts a proton in a chemical reaction. It can donate a pair of electrons to form a new bond with a proton. In water, Bronsted-Lowry bases can form hydroxide ions (OH-) when they accept a proton.
Depending on the type of acid/base (Arrhenius, Bronsted, Lewis), the acid donates protons and a base doesn't but accepts protons, or the base donates OH- and the acid doesn't, or the acid accepts a pair of electrons and the base donates a pair of electrons. They are just different, that's why.
A Lewis acid accepts an electron pair.
A Lewis acid.
The correct answer is acid.
The correct answer is acid.
A substance can be identified as a Lewis acid if it accepts an electron pair, and as a Lewis base if it donates an electron pair. Lewis acids are electron pair acceptors, while Lewis bases are electron pair donors.
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.

An acid is a substance that donates a proton or accepts an electron pair in a chemical reaction. Acids typically have a sour taste and can turn blue litmus paper red.
As the definition of a Lewis acid says:"Capable of accepting electron pair (from a (Lewis) base".So H+ and Ag+ are both Lewis acids compared in the following reaction with ammonia:(in which the N-atom is donating the unbound electron pair as being a 'Lewis' base)H+ + NH3 --> HNH3+Ag+ + 2NH3 --> Ag(NH3)2+[As you can see the 'Lewis' definition is much wider than the 'Bronsted/Lowry': it needs free places for an electron pair, not H+]
"Two of a kind" is one pair. Two pair beats one pair in any kind of poker.
