PPT-Uses of Alkalis and Chlorine

1 recall that even before industrialisation alkalis were needed to neutralise acid soils make chemicals that bind natural dyes to cloth convert fats and oils into soap and to manufacture glass. Drinking chlorine can make you very sick or kill you Do NOT drink chlorine or other liquids that have chlorine in them If you have been near a person with Ebola and have Fever Headache Muscle pain Vomiting Diarrhea Stomach pain Unexplained bleeding 7. understand that the . first . process for manufacturing alkali from salt and limestone using coal . as . a fuel caused pollution by releasing large volumes of an acid gas (hydrogen chloride) . and creating .

They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed.. It kills stuff ( ). Residual. It’s the law… But is it a good idea?.

A 5% solution of baking soda in water exhibits a pH of about 8 measured by a pH meter. A solution with pH 8 is con Providing a clean water source is essential to ensure optimal animal health and the best “bottom line.” Good, clean water begins with a thorough water line sanitation program.WATER-SMARTPROG DWQR Risk Assessment Training. 2018.
