Hydrogen peroxide is a weak acid. Generally, acids distinguishable by the hydrogen proton, while bases are generally anything with a hydroxide. For instance, hydrochloric acid, or HCl, can be distinguished by the H+ bonded with Cl-. NaOH on the other hand, is a bond between Na+ and OH-.
Indicate whether each of the following compounds will give an acidic, basic or neutral solution when dissolved in water. 1) ammonium bromide 2) ammonium perchlorate 3) calcium hypochlorite 4) potassium nitrate. Source(s): acid base chemistry question: https://biturl.im/21YnC. Monah Â· 2 months ago.est Answer: 1) The conjugate base of the ammonium ion is ammonia. The conjugate acid of the bromide ion is HBr. Hydrobromic acid is a strong acid, but ammonium is a weak base. The solution would be acidic. 2) The conjugate base is still ammonia.
