It is a Bronsted base.
Because a bronsted-lowry acid donates proton such as ( H+ ) and water can donate H+ such as ( H2O + NH3 ---> NH4+ + OH- ) here water donated H+ to ammonia to produce NH4 ( which is an acid )
A Bronsted-Lowry base is a proton acceptor.
A Bronsted-Lowry Acid Donates H+ ions
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.
It is a Bronsted base.
base
no, arhenious base is also a bronsted lowry base
As the name sulfuric acid might indicate, it is a bronsted-lowry acid.
base
It's a Brønsted Acid because it gives up a proton in water.
A Bronsted-Lowery base accepts H+ ions
Since protons are always transferred in the Arrenhius concept, all Arrhenius acid/base reactions are also Bronsted-Lowry acid/base reactions.
No, it is a niether bronsted lowry base nor bronsted acid. It is a lewis acid because it can accept electron pairs. For this to be a bronsted lowry acid, it would have to donate a proton, which this molecule is incapable of due to its electronic deficiency. I hope this helps.
Acid + base conjugate base + conjugate acid
The product will be a conjugate base.
The anion of Lowery-Bronsted acid acts as the conjugate base in this case, for example the conjugate base of HCl is Cl anion.
