Chapter 4.2, Problem 2PE

Interpretation Introduction

Interpretation:

The precipitate formed between $Al{(N{O}_3)}_3$ and $NaOH$ has to be identified and also net ionic equation for the reaction has to be written.

Concept introduction

Soluble substances are those which dissolve in a solvent. Insoluble substances are those which do not dissolve in a solvent.

A precipitation reaction is the reaction in which one of the product formed is an insoluble substance and remains separated from the solution as a solid.

Net ionic equation, which shows all species involved in the reaction.

Balancing the net ionic equation,

• Balanced molecular equation has to be written.
• Ionic equation has to be written, insoluble products has to be written as such.
• Identify and cancel the spectator ions.
• Check the charges and number of atoms and then balance.
