In our country ethanol is mainly manufactured by sugar industries the mother liquor lift behind after the crystallisation of sugar from sugar cane juice. What is denatured spirit?

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. In the brown solid precipitate, oxidation state of Mn is

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. The change of colour from green to purple is due to

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. In following reaction 3 K_2 underset("(green)")(MnO_4 + 2H_2 O + 4CO_2 to underset("(purple)")(2KmnO_4 )+MnO_2 + 4KHCO_3 the function of CO_2 is

Read the following passage and answer the questions given. The production and improper disposal of waste are causes for a great deal of environmental pollution. Many toxic industrial wastes from manufacturing process require treatment and /or safe disposal. When materials are recycled, apart from saving on the coast of raw material, waste disposal coast are reduced. Some combustible materials like dried leaves etc can be burnt to get heat energy. Sewage treatment includes filtering, scudge settlement, degradation coagulation disinfection using chlorine etc. Certain microorganisms can degrade waste in the absence of oxygen-digestion. Which of the following statements about sewage treatment is false?
