Chapter 17, Problem 17.109SP

Interpretation Introduction

Interpretation:

The metal ion ${\text{M}}^{\text{2+}}$ present in a metal nitrate solution, ${\text{M(NO}}_{\text{3}}{\text{)}}_{\text{3}}{}_{\text{(aq)}}$ has to be identified.

Concept Introduction:

Constant Current:

The number of coulombs of charge passed through the cell is equal to the product of current in amperes (coulombs per second) and time in seconds.  The constant current is calculated using the formula,

$\text{Charge(C)}\text{=}\text{Current(A)×Time(s)}$
