Answer to Question #182376 in General Chemistry for carly

Question

if HBr(at) has a molarity of 0.05 M, then the molarity of the {H3O+} ions is ___M

Answer 1

HBr is strong acid . It is completely ionizable in water.It is mono basic acid.

HBr(aq) + H2O(l) -----------> H3O^+(aq) + Br^-(aq)

0.05M ------------------------ 0.05M

[H3O^+] = [HBr] = 0.05M

[H3O^+] = 0.05M
