How to Determine the Position of Equilibrium

The conjugate acids have values of 0 and 10. Because the NH3 group is the weako acid, the NH2 group is the stronger base, so it is the group more apt to be protonated. 

Now use the skill you have just learned to solve Problem 12. 

Using the p T values in Section 2.3, rank the following species in order from strongest base to weakest base  

4 HOWTO PREDICT THE OUTCOME OF AN ACID-BASE REACTION 

Now let s see how we can predict that water will behave as a base when it reacts with HCl (the first reaction in Section 2.1) but as an acid when it reacts with NH3 (the second reaction in Section 2.1). To determine which of two reactants will be the acid, we need to compare their values.
