- anions travel towards it - cations travel towards it cathode- electrode at which reduction occurs * electrons travel from anode to cathode * * negative ions travel towards anode * Balancing Full Redox Equations Using Half Reactions: Ex.1
As + (ClO3)- --> H3AsO3 + HClO (acidic) As --> H3AsO3
3H2O + As --> H3AsO3 + 3(H+) + 3e- ClO3- --> HClO
4(e-) + 5(H+) + (ClO3)- --> HClO + 2H2O * now, multiply both equations to balance electrons * (oxidation) (redoxation) 12H2O + 4As --> 4H3AsO3 + 12(H+) + 12e- 3 x 4 x 12(e-) + 15(H+) + 3(ClO3)- --> 3HClO + 6H2O 3(H+) + 6H2O + 4As + 3(ClO3)- --> 4H3AsO3 + 3HClO * cancel electrons and any other common species * Ex.2
Cr + (ClO4)- --> ((CrO2)-) + (ClO3)- (basic) Cr --> (CrO2)-
2H2O + Cr --> ((CrO2)-) + 4(H+) + 3e- (ClO4)- --> (ClO3)-
2(e-) + 2(H+) + (ClO4)- --> ((ClO3)-) + H2O 3 x 4 x * now, multiply both equations to balance electrons * 4H2O + 2Cr --> 2((CrO2)-) + 8(H+) +6e- 6(e-) + 6(H+) + 3(ClO4)- --> 3((ClO3)-) + 3H2O H2O + 2Cr + 3(ClO4)- --> 2((CrO2)-) + 2(H+) + 3(ClO3)- * cancel electrons and any other common species * * now use the water equilibrium to cancel H+'s * 2(H+) + 2OH- <--> 2H2O 2Cr + 3((ClO4)-) + @OH- --> 2((CrO2)-) + 3((ClO3)-) + H2O Ex. Electrochemical Cell Cu + Ag+3 --> (Cu+2) + Ag Half-reactions:
Cu(s) --> (Cu+2) + 2e-
(Ag+3) + 3e- --> Ag(s) oxidation
reduction anode cathode Cell Potential:
E*cell = E*red - E*ox
E*cell = +0.80 - (+0.52)
E*cell = 0.28 V Mashkourine.. Mashkourine...
M. Hanoun :-) yours,
Ahmed Mukhlif Words can't decribe how thankful I am to all of you. Everybody has been a huge part of our success. I am proud of being a product of HMC Radiology, and I look forward to giving back as much as I can to my faculty and colleagues.
A special thank you goes to Dr. Omar, Dr. Adham and our core faculty for the extra time and effort they have given us.
Walid We did it! But who are we? We, The Radiology Dept! We worked together, hand in hand.. Faculty, Residents, everyone! We completed our residency and according to ACGME-I.... Now we are Competent! Let's pat ourselves on the back I would like to dedicate my accomplishment to my Grand Mom (My Allah blessed her soul) My Mom,my husband and all my advisors, professor , Consultants. The department administration staff, you left us with pleasant memories andmy colleague Shaima for your companionship
Salma I would like to express my great thankfulness and my appreciation of the extraordinary effort spent by our consultants, specialists all staff in the radiology department. As a result of your teaching and support, we achieved a great success and we promise to continue improving ourselves to the radiology department to be one of the sound departments in HMC! Thanks everyone Let's look at our journey First, we each want to give our individual thanks... Checklist
invitations Feb 9, 2013 :-) Thanks for everyone who have extended their kind and infinite support during residency. I only hope I can one day return the favor..
Couldn't have done it without you!!!
Jehan :-) LETS EAT! Thanks to my Lord, the most merciful. Thanks for everybody and best wishes for all my colleagues.
Tahera Thank you for all the assistance you have provided me during my Arab board exam.
Your cooperation and guidance has helped me at every step.
I appreciate the efforts and advices you have given, Your support and help have been invaluable during this process.
AMAL ALRASHID Cheerful events
The most cheerful event was being part of this wonderful team during my residency.
It is not only our success it is your sucess.
Thank you for the Dedication and Support
