Question

1. Consider the titration of 50.0 mL of 0.200 M HNO3 with 0.100 M NaOH solution. What volume of NaOH is required to reach the equivalence point in the titration?

a. 25.0 mL

b. 50.0 mL

c. 1.00 × 10^2 mL

d. 1.50 × 10^2 mL

2. Consider the following acid–base titrations: I) 50 mL of 0.1 M HCl is titrated with 0.2 M KOH. II) 50 mL of 0.1 M CH3COOH is titrated with 0.2 M KOH. Which statement is not true?

a. The initial pH of I is lower than that of II.

b. The equivalence point for I and II will occur at the same volume of base.

c. The equivalence point in I occurs at a lower pH than in II.

d. There will be a buffer region in both I and II

Answer 1

g red + Alol - Ill & H₂O at equivalence point, pH wall be 7. CA won t kon – CH₂ cookt +40 CH₂ workt is a salt- of Strong base 30, it will have basic prat - equivalence point which is greater than 7. d) Hel is a strong acid buffer So, it will not have region o (D) is incorrect Statement answer is
