Question

Question 1 1 pts Consider a solution that is 0.1 M HF and 0.1 M NaF. This is a mixture of conjugates in equal proportions, which tells you that it is a buffer. What two reactions are relevant to the pH in this situation? NaF --> Nat + F F+H2O <--> HF + OH- HF + NaF --> H+ +Na+ + F2 HF <--> H+ +F Ht+F<--> Nat + F"

Answer 1

1 ans - log [ht pH Therefore reaction F +H2O HF TOH and HE > H+ +E are gielevent to the pH of the solution. 2 Ans A buffer o muxture acetate containing of acetic acid (CH3 COOHY and its congregate. base ie If strong acid (H+) is added to this buffer the conjugate acetate will consume the (H+) auld hence the concentration of CH2OoH increases and conuntoration of CH3.co0 dequeeses • Thes situation Shown by the Meaction: CHg.cod® caq) + Haq - CH₂ coolt lag)
