how bleaching powder,baking soda,washing soda,baking powder,slake lime are prepared
Answers
Answer:
1: bleaching powder= chlorine is produced during the electrolysis of Aqueous sodium chloride brine the this chlorine gas is used for manufacture of bleaching powder. bleaching powder is produced by the action of chlorine on dry slaked lime bleaching powder is represented by caocl2 do the actual composition is quite complex.
Ca(OH)² + CL² ------- CaOCL² + H²O
2: baking soda:
the chemical name of the compound is sodium hydrogen carbonate (NaHCO³). it is produced using sodium chloride as one of the Raw materials.
NaCL + H²O+ CO²+NH³ –––. NH⁴CL + NaHCO³
3: washing soda:
it can be obtained from sodium chloride is Na²CO³.10H²O. Recrystallization of sodium carbonate gives washing soda.
Na²CO³ + 10H²O --------- Na²CO³.10H²O
Answer:
Bleaching powder is also called as chloride of lime or chlorinated lime. The chemical name for Bleaching powder is Calcium Oxycloride. Bleaching powder is prepared by passing gas state of chlorine over dry slaked lime (`Ca(OH)_2` ), this process will gives bleaching powder.
I think this is the right answer for your question.
