Along with it, barium bromide reacts with oxygen, sulfur, and carbon to form barium compounds. In aqueous solution, classify these compounds as strong acids, weak acids, strong bases, weak bases, or other. The \(Cl^\) ion is the conjugate base of the strong acid \(HCl\), so it has essentially no basic character (Kb < 1 x 10-14). In essence, you can go from an acid to its conjugate base by removing a proton, and from the conjugate base to the original acid by adding a proton. Our videos prepare you to succeed in your college classes. In water it loses its acidic hydrogen to the water molecule as H+ ion.
