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-.
Best Answer: Conjugate bases and acids occur with weak acids, such as acetic acid. I'll use an example to answer this question: ---acetic acid = (HA) = weak acid The conjugate base of acetic acid (HA) is (A-) ...(-) is a superscript.So, the conjugate base of acetic acid is a molecule of acetic acid missing an electron, or a hydrogen, and has a negative charge.Specifically, the conjugate base of acetic acid is Na+Acetate. The Na+ atom, with a positive charge is used to balance the negative charge of the conjugate base.he conjugate base of a weak acid is a strong base, and the conjugate base of a strong acid is a weak base, and vice versa. Conjugate Base: The conjugate base of a weak acid is a strong base, and the conjugate base of a strong acid is a weak base, and vice versa.
