In water it loses its acidic hydrogen to the water molecule as H+ ion. In an acid/base reaction will there always be an acid and always be a base? - neutral (NH 4 + is a weak acid, but C 2 H 3 O 2-is a weak base - the conjugate base of a weak acid, HC 2 H 3 O 2. Why do small African island nations perform better than African continental nations, considering democracy and human development? g) Acidic h) Basic Reason: g) It is a conjugate of a weak base (ammonia) and strong acid ( H2SO4) hence it is acidic as its acidity is higher h) All metal oxides are basic or, metal conjugates are all basic and oxides are neutral (not sure about the oxide one) Dies geschieht in Ihren Datenschutzeinstellungen. ISBN: 9781305957404. bonjourr bonjourr CH3NH3Cl acidic basic neutral KC104 acidic basic neutral COF2 acidic basic neutral. The conjugate acid of HC3NH2 is CH3NH3^1+ Conjugate acid of Ch3NH2? Identify the following as an acidic salt, basic salt, or In case you did not know, the part of the salt from the weak acid removes some of the H+ ions from the water equilibrium causing changes in this equilibrium that result in [OH-] increasing.
