In Chemistry, Bronsted-Lowry acid refers to any chemical species of element that is capable of donating a proton ([tex]H^+[/tex]). Thus, a [tex]K^+[/tex] ion is an example of a Bronsted-Lowry acid.
In conclusion, [tex]K^+[/tex] ion is acidic in water because it makes hydrating water molecules to become much more acidic in accordance with the Bronsted-Lowry acid theory.
