Chapter 15.6, Problem 15.8P

Interpretation Introduction

Interpretation:

Net ionic equation for reaction indicated has to be written.

  ${\text{3H}}_{\text{2}}\text{S}\left(s\right)+\text{2Bi}{\left({\text{NO}}_{\text{3}}\right)}_2\left(aq\right)\to {\text{Bi}}_{\text{2}}{\text{S}}_{\text{3}}\left(s\right)+6{\text{HNO}}_{\text{3}}\left(aq\right)$

Concept Introduction:

The ionic equation can be written based on the rules as follows:

• Strong electrolytes dissociate completely into ionic forms.
• Weak electrolytes remain in molecular form.
• Nonelectrolytes remain in molecular form.
• Insoluble precipitates, and gases remain in molecular forms.
• The net ionic equation includes only ions that have reacted and thus any spectator ions are usually omitted.
