Ph of kbr in water
WebAug 21, 2011 · The conjugate base of a weak acid is in fact basic in solution, raising the pH above 7. Both HBr and KOH are strong acids and bases, respectively. Conversely, Br- and K+ must be very very weak bases. Because they are so weak their effect on the pH of a solution is negligible. Top 2 posts • Page 1 of 1 Return to “Conjugate Acids & Bases” WebAug 31, 2024 · $\begingroup$ I see the term acidic is in the question context used in ambiguous way. acidic(1) as being an acid, acidic(2) as forming solution with pH<7. While bicarbonate solution is acidic(1), as HCO3- is a weak acid, it is not acidic(2), as HCO3- is also a not so weak base. $\endgroup$
