ANSWER:
Solution 43SP
Step 1
When arranging species in order of increasing basicity, it’s important to look at the conjugate acid of the base. If the conjugate acid is weak (and this can be determined by looking at a table of values), the corresponding base will be strong. You can therefore use a table to determine the relative basicity of different species.
