For example, our blood, our blood has much more conjugate base than conjugate acid. But that's because our body produces many more acidic byproducts than basic byproducts. And so we need more base to neutralize our acid. Now, let's see how these buffers work. So, for example, suppose we have the buffer system above, composed of acetic acid methodate ion. Now, suppose we add a strong base such as sodium hydroxide to our system.
