PPT-Preparation of sodium hydroxide

What ıs sodium hydroxide Sodium hydroxide is one of the most common inorganic bases or alkalis It is also called caustic soda or lye Formula and structure The chemical formula of sodium hydroxide is . 6 mg of CO 2 The conversion is as follows Carbonate Alkalinity as CO 2 mgL 06 Carbonate Alkalinity as CaCO mgL Converting Bicarbonate Alkalinity from mgL as CaCO to mgL as HCO Consider the following reaction CaCO H O CO CaHCO CaCO has a molecular . and. . Alkalis. T. . Sudarat. . Khampa. Acids. Latin word ‘. acidua. ’ : sour. Has a sour test. Has a pH value less than 7. Has a corrosive nature. Turns blue litmus paper red. Reacts with reactive metals to produce hydrogen gas. . HAIR. RELAXERS. CHEMICAL HAIR RELAXERS. Chemical hair relaxing is the process of rearranging the basic structure of extremely curly hair into a straight or less curly form.. The chemical process is very similar although the results are opposite from permanent waving hair.. Neutralisation reactions. Acids and bases . are opposite. One makes pH lower and the other makes pH higher. When acids and bases react they make pure water and a salt. Because pure water is pH 7 (neutral), this reaction is called a neutralisation reaction.. antacids. Acid indigestion/heartburn. Acid indigestion (discomfort in stomach) and heartburn (acid rising into . oesaphagus. ) are conditions which arise when excess hydrochloric acid is produced by the gastric glands in the walls of the stomach. The acid, which creates an acidic environment of pH 0.3 to 1.2 is needed to. 3. understand that alkalis neutralise acids to make salts. 4. recall that soluble hydroxides and carbonates are . alkalis (Higher). 5. predict the products of the reactions of soluble hydroxides and carbonates with . Day 3. Naming Acids. Acids usually have H as the cation. . H. Cl. Acids are named depending on whether they are oxyacids (ternary acids) or non-oxyacids (binary acids). The elements in group 1, on the left of the periodic table, are called the. . alkali metals. ..
