True'and false please with brief explanation. True or False1. A buffer composed of a weak acid ofpKa = 6 is stronger at pH 5 than at pH%3D7.2. At pH values higher than the pKa, thesalt concentration is higher than that ofthe acid.3. The pH of a buffered solution remainsconstant no matter how much acid orbase is added to the solution.4. The strongest buffers are thosecomposed of weak acids and weakbases (not strong).5. When pH = pKa, the weak acid and saltconcentrations in a buffer are not equal.
