Buffers ranges

WebThe buffer range is the pH range over which a buffer acts effectively. Buffer capacity - the number of moles of acid or base that must be added to one liter of the buffer solution in order to lower or raise the pH by one unit. The more similar the concentration of the two components, the greater the buffer capacity. WebThe buffer range is the range of pH values over which a buffer is most effective (i.e. has the largest buffer capacity for its concentration). A good buffer mixture should have …

WebSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one.
