Chapter 18, Problem 18.14P

Interpretation Introduction

Interpretation:

The time required before the steel is exposed under given conditions should be determined.

Concept Introduction:

Time required for plating before exposing is calculated by,

  $t=\frac{wnF}{IM}$

Where,

w = mass of substance/metal

n = charge of metal ions

F = Faraday's constant

I = current in the cell

M = atomic mass of metal
