Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH 3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.
The NO3- anion is the conjugate base of a strong acid (HNO3) and is therefore pH-neutral. 608 Chapter 15 Acids and Bases (c) The CH3NH3+ ion is the conjugate acid of a weak base (CH3NH2) and is therefore acidic.The CH3NH3NO3 solution will be acidic. The NaCHO2 solution will be basic.o determine the overall acidity or basicity of the solution, compare the values of Ka for the acidic cation and Kb for the basic anion. The F-ion is the conjugate base of a weak acid and is therefore basic. basic anionacidic cationNH4F Ka(NH4+) =KwKb(NH3)=1. Since Ka is greater than Kb, the solution is acidic.
