Chlor-alkali is an industrial process widely used to produce chlorine‚ caustic soda‚ and other chlorine and sodium derived/based products such as sodium hypochlorite‚ hydrochloric acid‚ chlorosulphonic acid‚ bleaching power‚ polyaluminium chloride‚ hydrogen gas‚ and chlorinated paraffin. The process uses brine (sodium chloride) solution during electrolysis to produce aforesaid products which are also known as Chlor-Alkali Industry /market products. The report estimates the market size of Chlor-Alkali

Soda ash and materials made from it can be found in most industries. In modern times‚ it is used in the manufacture of soap‚ glass‚ and paper. It is also used the ultimate analysis of coal and tar.2 Soda ash is commonly manufactured using the Solvay process in which CO2 is bubbled through a concentrated sodium chloride solution at 0 oC and saturated with ammonia. Sodium hydrogen carbonate precipitates from the solution and is isolated. Heating the solution to 300oC allows the sodium hydrogen carbonate

water treatment etc. It can be a pure compound of sodium carbonate‚ sodium bicarbonate or sodium hydroxide or the mixture of the three with compatible percent compositions. These compositions are determined by acid-base titrations‚ a volumetric process in determining the concentration of a substance in a certain solution which uses a base or acid as the titrant. Experimental Section A. Preparation and Standardization of 0.10 M HCl Solution In preparing the HCl solution‚ 500 mL of distilled

109 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction- This experiment is intended to help find a better understanding of chemical stoichiometry through titrations of NaHCO3 and NA2CO3 with HCl. A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance‚ as opposed to a change in physical form in a nuclear reaction. Titration is when a measured amount of solution of unknown volume is added to a known volume of a second

Let’s Make Salt Purpose: Could NaCl be made using NaHCO3‚ hydrochloric acid‚ and a boiling chip? Hypothesis: If I combined NaHCO3‚ hydrochloric acid‚ and a boiling chip I think it will form NaCl because when you balance the equation it makes a new chemical reaction. Materials needed: test tube cleaner‚ test tube‚ test tube tongs‚ hot plate‚ a scale‚ graduated cylinder‚ water‚ goggles‚ fire retardant glove‚ beaker‚ test tube holder‚ a scoopula‚ hydrochloric acid‚ sodium bicarbonate‚ soap‚ pipette
