difference btwn acid & base

Postby Gwynneth Orlino 1B » Mon Jul 29, 2019 1:48 pm

What's the difference between Bronsted acids and Bronsted bases? What is a conjugate base and a conjugate acid?

Bronsted acids by definition can donate protons (ie release H+). Bronsted bases can accept protons (ie form a bond with H+). The conjugate base of an acid is the species that results when the acid donates its proton. For example, Cl- is the conjugate base of the acid HCl. Similarly, a conjugate acid is the species that results when a base accepts a proton eg the base NH3 accepts a proton and forms its conjugate acid NH4+ . We call NH4+ the conjugate acid of NH3 because in the reverse reaction, NH4+ can donate a proton, making it an acid, to reform NH3.
