Chapter 17: Q1TY (page 398)

A monolayer (single layer of atoms) of Cuon the (100) crystal face shown in the margin has1.53脳1015atoms/cm2=2.54脳10-9mol/cm2. What current can deposit one layer of Cuatoms on1cm2in 1 s?

Short Answer

Expert verified

The current required to form a monolayer of copper atoms is 0.4.90mA.

Step by step solution

01

Define electric circuit

At any point in an electric circuit the charge is the product of current I and time t.

q = I.t

The unit of q is Coulombs, I is Ampere and t is seconds

q=molesofelectrons脳Faraday'sconstant

02

Determine the current required to form a monolayer of copper atoms.

Number of electrons required to deposit copper is two. Then number of moles of copper is

Moles of copper=2脳2.54脳10-9

=5.08脳10-9mol

q=molesofelectrons脳FaradayconstantIt=molesofelectrons脳Faraday'sconstantI=molesofelectrons脳FaradayconstanttI=(5.08脳10-8mol脳96485C/mol)1s

I=0.490mA

The drug Librium gives a polarographic wave withE1/2=-0.265V(versus S.C.E.) in 0.05MH2SO4. A 50.0 - Mlsample containing Librium gave a wave height of0.37渭A. When 2.00mLof 3.00mMLibrium in0.05MH2SO4were added to the sample, the wave height increased to0.80渭A. Find the molarity of Librium in the unknown.

Explain what is done in anodic stripping voltammetry. Why is stripping the most sensitive voltammetric technique?

17-16. The sensitivity of a coulometer is governed by the delivery of its minimum current for its minimum time. Suppose thatcan be delivered for 0. 1s.

(a) How many moles of electrons are delivered by 5mAfor 0. 1s ?

(b) How many millilitres of a 0.01 Msolution of a two-electron reducing agent is required to deliver the same number of electrons?

(a) At what cathode potential will Sb(s)deposition commence from 0.010MSbO+solution at pH 0.00? Express this potential versus S.H.E. and versusAg|AgCI. (Disregard overpotential, about which you have no information.)

SbO++2H++3e-鈫�Sb(s)+H2OE掳=0.208V

(b) What percentage of0.10MCu2+could be reduced electrolytically to Cu(s)before0.010MSbO+in the same solution begins to be reduced at pH 0.00?

A dilute Na2SO4solution is to be electrolyzed with a pair of smooth Pt electrodes at a current density of 100A/m2and a current of 0.100A. The products areH2(g)andO2(g)at1.00barandatbar. Calculate the required voltage if the cell resistance is2.00惟and there is no concentration polarization. What voltage would be required if the Pt electrodes were replaced by Au electrodes?
