And this is a very high value. And what that or a relatively high value. And what that means is this will not be a good enough acid. And if it's not a good enough acid, it will not be very likely to produce this hydroxide ion. And as we'll see in just a moment, it's the hydroxide ion that will be much more likely to act as a nucleophile and attack the carbon dioxide than the water. Now, what this binding does is because of this association, this reaction, the dissociation of that H plus ion to form the hydroxide and the H plus greatly increases.
