Homework Answers
KOH + HCOOH = acidic buffer having PH 5 - 6.5
Because it is mixture of weak acid and strong base. here strong base( KOH ) are present in small amount which react with weak acid HCOOH and form salt of weak acid with strong base which is neutral . but here still HCOOH are present so final solution is acidic. and since HCOOH is not 100% ionizable acid so PH is also near 5 to <7.
KOH + H3PO4 = Acidic buffer.
here H3PO4 is weak acid which mixed with strong base nd form salt. same explanation as explained in above case.
