Question

Item 5 Review Constants Peris You may want to reference (Pages 795 -812) Section 174 while completing this problem Previous Consider the following curve (Figure 1) for the titration of a weak base with a strong acid and answer each of the following questions ✓ Correct At the equivalence point the added acid has neutralized the weak base, leaving only the conjugate acid affecting the pl is ao why the equivalence point occurs at an acidic pH Figure 1 of 1 > Beyond what volume of added acid is the pH calculated by focusing on the amount of excess strong and added? Express the volume in m ers as an integer. IVO AXO O ? pH Submit Request Ans 0 10 20 30 40 50 Volume of acid added (mL) provide Feedhack

Answer 1

Solution As per given in the question Pert let weak base is krin After Acid-Base Neutralisation between weak cabe and strony mid, the remaining Conjugated Acid is R-ning the rain w.3. - Sot But this conjugated acid hydrolysed according to given reachon R-Nyt + ho ² Ring + hot Que to hydrolysis the pH at Equivalent point is <7 Part F - it is clear from graph that after aumi ( the ph of solution is mainly focus on volume of acid .
