Chapter 21, Problem 116IL

(a)

Interpretation Introduction

Interpretation:

To write the balanced equation for the reaction of ${\text{NaBH}}_{\text{4}}$ with ${\text{AgNO}}_{\text{3}}$ in water.

Concept introduction:

Reducing agent are the species that reduces another species and itself gets oxidized in a chemical reaction. A common example of reducing agent is sodium borohydride. The formula for sodium borohydride is ${\text{NaBH}}_{\text{4}}$. It reacts with compounds having metal ions and reduces them to free metal.

A balanced chemical equation occurs when the number of atoms in reactant side is equal to the number of atoms in the product side.

(b)

Interpretation Introduction

Interpretation:

The mass of silver produced in the reaction has to be stated.
