SCS3111: INORGANIC AND PHYSICAL CHEMISTRY [45 LH]
PURPOSE OF THE COURSE
To impart knowledge to the learners on inorganic and physical chemistry and create an understanding on the role of chemistry in everyday life and apply it in agricultural sciences.
EXPECTED LEARNING OUTCOMES
By the end of the course the learner should be able to:-
- Calculate simple changes in simple reactions and describe atomic spectra and explain its relation to electronic arrangement.
- Describe radioactivity and nuclear reactions in relation to agriculture.
- Carry out calculations on pressure –volume, pressure-temperature, volume-temperature relationship and explain the difference between real and ideal gas.
- State, explain and calculate pH, pK, degree of dissociation of acid/base solution, buffers.
- Define and explain electrode potential and calculate E-cell and apply electrode potential information in protecting environmental from pollution.
