Chapter 15, Problem 15.93QE

(a)

Interpretation Introduction

Interpretation:

Whether the solution of $1M{\text{ FeCl}}_3$ is acidic, neutral, or basic has to be stated.

Concept Introduction:

Spectator ions are regarded as ions that do not appear in the net ionic equation of an acid base reaction. This is because they are usually the conjugate base corresponding to strong acids such as chloride, iodide, bromide, or nitrate ions.

Brønsted–Lowry acid transfers a proton and form base as the other compound that can accept a proton. This is called conjugate acid-base pair. In pair of conjugate acid and base, the acid form is protonated and the base form lost the proton.

(b)

Interpretation Introduction

Interpretation:

Whether the solution of $1M{\text{ BaI}}_2$ is acidic, neutral, or basic has to be stated.
