Chapter 16.9, Problem 1RC

(a)

Interpretation Introduction

Interpretation:

The weakest anion has to be identified from the three ${\text{X}}^{\text{-}}$ of salts $\text{NaX (X=A, B, or C)}$

Concept Information:

Salt hydrolysis is a reaction in which the ion of salt reacts with water and produce either hydronium ion or hydroxide ion.

Based on ions produced in solution through salt hydrolysis, the salt can be classified as,

• Acidic
• Basic
• Neutral

$Conjugateacid =Base+H^{+}$

$Conjugatebase =Acid-H^{+}$

Conjugate acid-base pairs differ by only one proton.

(b)

Interpretation Introduction

Interpretation:

The three ${\text{X}}^{\text{-}}$ anions from three salts $\text{NaX (X=A, B, or C)}$ has to be arranged in order of its increasing base strength.

Concept Information:

• Salt hydrolysis is a reaction in which the ion of salt reacts with water and produce either hydronium ion or hydroxide ion.
• Based on ions produced in solution through salt hydrolysis, the salt can be classified as,
  • Acidic
  • Basic
  • Neutral
