Role of Chemistry in the Society

Roles of Chemistry in the Society

Introduction

Chemistry is a science that embrace the concept of creation of molecules and the manipulation of atoms and dealing with microscopic and nanoscopic scales. It covers interactions with plants, animals through agriculture, biology and medicine and with physical world through electronics, new building materials and new sources of energy.
Everything that we hear, smell, see, taste and touch involves chemistry and chemicals. The knowledge of chemistry in society is therefore important because;


  1. Chemistry is vital to our society because it impacts us on the knowledge of good health and maintenance of it. When applying to study medicine, applicants are expected to have thorough knowledge of chemistry before even beginning their degree. Chemistry is vital for the study and development of medicine as it allows to find out how illness and diseases can be cured with minimal effects on the patient i.e. it helps to prevent pain and live longer, happier and healthy lives.
  2. Through the knowledge of chemistry, it has been possible to explore space i.e. space exploration by scientist. Through it, there is invention of liquid oxygen a key component in rocket fuel. The space race would not have happened and the related technologies society gained from it such as the internet and satellite television would not exist.
  3. The concepts in chemistry e.g. extraction of medicine from trees etc. have improved the people’s health in society. Humans would still be plagued by illness such as small pox and polio and penicillin would not be available to fight bacterial infections.
  4. Today, people have prolonged their lives using medicine i.e. they can live rather healthy and rely on medicines, drugs and vaccines from birth to death.
  5. Chemistry is the integral part of society and environment. The battery we use in torch, music player etc. are working by the principle of electrochemistry and without the knowledge of chemistry, it could have been difficult to produce such batteries. 
  6. Knowledge of Chemistry is useful in production of soaps and detergents-by esterification of fatty acids with base like sodium hydroxide etc. Without the knowledge of chemistry, it could have been difficult to produce this products.
  7. Chemistry is important in nutrition i.e. without the knowledge of Chemistry, we cannot determine that the food that we are eating is expired, we do not know how to analyses the composition of certain substances to formulate new products and develop better manufacturing process.
  8. Knowledge of chemistry is important in agricultural production. It has led to manufacturing of better chemical fertilizers in accordance with the soil type which consequently increases the agricultural production. It has also make it possible to interbreed genetically close species in biology through extraction of DNA from the parents e.g. polyploidy in wheat which have increased the wheat production.

Conclusion

In the longer run, Chemistry is going to create materials with extraordinary properties which will dramatically improve communications, health care, environmental monitoring and transport. Chemistry will stimulate and support innovation in all of the other branches of science and technology.

Application of EMF Measurements

Application of EMF Measurements i) Determination of Equilibrium Constant Measurement of the standard Emf of the cell, E° Cell , enables one to evaluate the equilibrium constant for the electrode reaction. The relation between the standard free energy change and the equilibrium constant of a reaction is given by: G 0 = -RT In K But the standard free energy is related to the standard electrode potential by the expression: G 0 = -nE 0 F  Hence E 0 = In K At 298K E 0 = log K                                                                                                                   Exercise 4 For the following electrochemical cell Zn/Zn 2+ //Fe 3+ ,Fe 2+ /Pt Whose standard Emf is 1 .534V, the overall cell reaction is Fe 3 + + 1/2Zn  Fe 2+ +1/2 Zn 2+ ii) Determination of Solubility Products This is a useful technique to evaluate the solubility product of sparingly soluble salt such as AgCI. The saturated solution of AgCl in water is so dil

Limiting Molar Conductances of Weak Electrolytes

Limiting Molar Conductances of Weak Electrolytes One of the immediate application of Kohlrausch’s law at infinite dilution is the   determination of the limiting molar conductance at infinite dilution m   of weak electrolytes. These values cannot be determined by extrapolation of a plot of m versus √C (see fig 2) as in the case of strong electrolytes. In the case of weak electrolytes, an indirect method is employed For example in the case of acetic acid, its m  may be determined indirectly as follows; m ( CH 3 COOH) = m  (CH 3 COONa) + = m (HCl) - m (NaCl) =91.0+425.0-126.5 = 389.5 -1 cm 2 mol -1 or simply; m ( CH 3 COOH) =  CH3COO - + H + = 40.9 + 348.6 = 389.5 -1 cm 2 mol -1

Validity and Reliability of a Test

Validity and Reliability of a Test    Introduction   An important part of social science research is the quantification of human behavior that is, using measurement instruments to observe human behavior. The measurement of human behavior belongs to the widely accepted positivist view, or empirical-analytic approach, to discern reality. Because most behavioral research takes place within this paradigm, measurement instruments must be valid and reliable. Reliability Reliability is the extent to which measurements are repeatable –when different persons perform the measurements, on different occasions, under different conditions, with supposedly alternative instruments which measure the same thing. In sum, reliability is consistency of measurement (Bollen, 1989), or stability of measurement over a variety of conditions in which basically the same results should be obtained. Methods of testing reliability   Because reliability is consistency of measurement over time o
