Use these guidelines for all questions remaining in this assignment. For all reactions below the species in the reaction are numbered 1, 2, 3 and 4 from left to right. Answer the following questions with the appropriate number to identify the species that is asked. Assume that the reactions are being read from left to right. For example if in the reaction shown below you are asked which species is the acid
NH₃ + HNO₂ <=>NH₄⁺+NO₂⁻
You would then answer with the number 2.
So for this reaction shown which species is the conjugate base?
