Why demand analysis of caustic soda? 2.1 CAUSTIC SODA Sodium hydroxide‚ also known as caustic soda‚ or lye‚ is an inorganic compound with the chemical formula NaOH. It is a white solid and highly caustic metallic base and alkali salt which is available in pellets‚ flakes‚ granules‚ and as prepared solutions at a number of different concentrations. Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water. Sodium hydroxide is soluble in water‚ ethanol and methanol. This

orbital. Group 11 &12 elements i.e. Cu & Zn have bigger size due to strong shielding of completely filled (n-1)d orbital. The transition elements show variable oxidation state due to small energy difference between (n-1)d &ns orbital as a result both (n-1)d &ns electrons take part in bond formation. The highest oxidation state of an element is equal to number of unpaired electrons present in (n-1)d &ns orbital. Transition elements have high enthalpy of atomization/ sublimation Because

Contents Chapter 1. Introduction and scope development Brewing is an energy intensive process requiring large amounts of water consumed in the brewing process as well as washing and sterilizing procedures. It is estimated that between 4 and 7 L of water is required to produce 1 L of beer. Beer is the fifth more popular drink in the world so to meet this demand; large quantities of water are required. Water chemistry has an effect on the brewing efficiency as well as the

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such

At each disinfection treatment‚ minimally processed calçots were immersed in 10 L disinfectant solution at room temperature under continuous agitation (x rpm) for 60 s. For all washing solutions‚ pH and oxidation-reduction potential (ORP) were determined before and after calçot treatment (Table 1). Free chlorine and peracetic acid was determined using a free and total photometer (HI 93734‚ Hanna Instruments‚ Eibar‚ Spain). ORP and pH were determined using

In the IUPAC system of nomenclature‚ functional groups are normally designated in one of two ways. The presence of the function may be indicated by a characteristic suffix and a location number. This is common for the carbon-carbon double and triple bonds which have the respective suffixes ene and yne. Halogens‚ on the other hand‚ do not have a suffix and are named as substituents‚ for example: (CH3)2C=CHCHClCH3 is 4-chloro-2-methyl-2-pentene. If you are uncertain about the IUPAC rules for nomenclature
