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
