Question

How many moles of HCOONa must be added to 1L of 0.1M HCOOH to prepare a buffer solution with a pH of 3.4

Answer 1

HEY DEAR ........!!!!!

 

“A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. Many life forms thrive only in a relatively small pH range; an example of a buffer solution is blood.” 

the answer is 0.05
