What is a buffer solution, Type , how can calculate and applications?
This questions will be answered by any textbook on general or physical chemistry, also by books on physiology or biochemistry.
Hi,
Buffer is primarily a solution that can resist the variation in pH of a solution at a specific pH range. The buffer comprises the weak acid or weak base in a solution. For example- we cannot make a buffer with HCL because, this is a strong acid. It has to be something like HNo2 or Nitrous acid because its a weak acid.
In addition to this, we should have weak acid or weak space conjugates. So, we need to put the salt that contains the conjugates of that weak acid or weak base. A conjugate is a compound that is differ by the one proton. for example - NH3 and NH4+. So here is a difference of one proton. and, these are termed as the conjugate pairs.
For more understanding, I have attached one of the best book. Go through the 2nd chapter of this book.
A buffer, is a solution that can maintain pH of a solution and resist pH change upon the addition of an acidic or basic components to that solution.
Buffer solutions can only be able to neutralize just small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.
