CHAPTER I THE PROBLEM Introduction Folktales are one of the forms of prose narrative which we regarded as fiction. They are not considered as dogma or history‚ they may or may not have happened‚ and they are not to be taken seriously.1 However‚ folktales like other stories provide various experiences that is why they are important. Folktales are not merely stories but there are morals in them‚ probably not obvious but underlying morals in it. In like manner‚ folktales may not be history

Determination of Ka for a Weak Acid Introduction In the experiment preformed the objective is to titrate a weak acid with a strong base. In a titration of a weak acid with a strong base the titrant is the strong base and the analyte is a weak acid. The reaction that will occur is the direct transfer of protons from the weak acid to the hydroxide ion. The data gathered will be represented on the titration curve‚ a graph of the volume of titrant being the strong base plotted against the pH .The

Ancient Egyptians had a strong belief in preserving the body for the afterlife in hopes of achieving immortality. Part of this preservation was to protect and identify the body by painting or carving pictures‚ hieroglyphics‚ and symbols on the coffin. One very good example of this is represented by the ‘Mummy of Irethorrou in Coffin.’ This coffin‚ made of wood with polychrome‚ is adorned with hieroglyphics‚ symbols‚ and a portrait of the Egyptian priest. It was found in a cemetery in Akhmim‚ and

the acid ionization constant‚ Ka. The equation for Ka incorporates the concentration of water as a constant value. Ka = [ H3O+][A-] [HA] and Ka = Kd [H2O] Organic acid ionization constants can cumbersome to work with because they are often very small numbers. Acetic acid‚ for example‚ has a Ka is value of about 0.00001 (or 10-5)‚ phenol has a Ka of 10-10. It is usually more convenient to use a logarithmic scale to handle these numbers. Accordingly‚ Ka values are transformed to pKa values

1. Adsorption: Concentration of liquid or gaseous molecules over the surface of a solid material is known as adsorption. It is a surface phenomenon. (e.g.) H2 adsorption over nickel. The solid material is known as adsorbent. (e.g.) Nickel‚ Silica gel‚ Charcoal‚ Zeolite The gaseous or liquid molecules are adsorbate (e.g.) H2 gas‚ Bromine‚ benzene‚ water vapour For gases‚ a special name is given as “occlusion’ 2.If the concentration is of bulk phenomenon‚ it is absorption

Poetic Elements in Sande¿ak¡vyas Introduction Sanskrit is the vast and rich treasure house of various branches of knowledge. It has produced magnificent and sublime poetry since time immemorial. Ancient Indian thinkers thought a lot on the various aspects of poetry from different angles and consequently criticism of poetry developed here. New views emerged‚ several literary principles were explored and a series of schools of poetics came into existence. Sanskrit poetics is remarkably rich. Inasmuch
