10. will the solutions obtained by mixing solutions have a buffering effect:
a) hcoona (v = 10 mj, c=0,1 mojl/ji) and hci (v=10 mj, c=0,08 moj/);
b) hcoona (v = 10 mji, c=0,1 mojb/11) and hcooh (v=5 mj, c=0,01 moj/a).
for one of the buffer solutions:
1) calculate the ph of the solution;
2) indicate by acid or base the buffer capacity of this solution is greater, justify the answer,
3) determine how the ph of the prepared solution changes:
a) with the addition of 10 ml of 0.01 n hci
b) with the addition of 10 ml of 0.01 n naoh;
4) suggest methods for preparing this buffer solution.
5) write a buffering mechanism.
