Chapter 20, Problem 19QAP
Interpretation Introduction

(a)

Interpretation:

The balanced chemical equation for the reaction where chromate ions react with strong acid should be determined.

Concept introduction:

A balanced chemical reaction equation is the one in which the number of atoms of all the elements are equal on both the sides of the chemical equation.

Interpretation Introduction

(b)

Interpretation:

The balanced chemical equation for the reaction where the oxidation of water to oxygen takes place in the presence of permanganate ions in basic solution should be determined.

Concept introduction:

A balanced chemical reaction equation is the one in which the number of atoms of all the elements are equal on both the sides of the chemical equation. An oxidizing agent is the one which has the tendency to oxidize others and itself gets reduced in a chemical reaction.

Interpretation Introduction

(c)

Interpretation:

The balanced half reaction equation for reduction of chromate ion to chromium (III) hydroxide in basic solutions should be determined.

Concept introduction:

A balanced chemical reaction equation is the one in which the number of atoms of all the elements are equal on both the sides of the chemical equation. Reduction of a chemical species is said to occur when the oxidation state of the species undergoing reduction decreases due to gain of electrons.

Briefly state why trifluoroacetic acid is more acidic than acetic acid.
Explain why acid chlorides are more reactive than amides in reactions with nucleophiles.
Calculating the pH of a weak base titrated with a strong acid An analytical chemist is titrating 101.7 mL of a 0.3500M solution of piperidine (C5H10NH) with a 0.05700M solution of HClO4. The pK of piperidine is 2.89. Calculate the pH of the base solution after the chemist has added 682.9 mL of the HClO solution to it. 4 Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HClO solution added. 4 Round your answer to 2 decimal places. pH = .11 00. 18 Ar
