ENGINEERING CHEMISTRY – II |
UNIT I ELECTROCHEMISTRY |
Electrochemical cells – reversible and irreversible cells – EMF – measurement of
emf – Single electrode potential – Nernst equation (problem) – reference
electrodes –Standard Hydrogen electrode -Calomel electrode – Ion selective
electrode – glass electrode and measurement of pH – electrochemical series –
significance – potentiometer titrations (redox - Fe˛+ vs dichromate and
precipitation – Ag+ vs CI- titrations) and conduct metric titrations (acid-base – HCI
vs, NaOH) titrations. |

different types – galvanic corrosion – differential aeration corrosion – factors
influencing corrosion – corrosion control – sacrificial anode and impressed
cathodic current methods – corrosion inhibitors – protective coatings – paints –
constituents and functions – metallic coatings – electroplating (Au) and
electroless (Ni) plating. |
