So what happens is that you get a solution of sodium hydroxide from the reduction of water at the anode, and chlorine gas from the oxidation of chloride at the cathode. Some Cl2 will probably come up out of the solution, but a lot of it will redissolve into the NaOH solution giving ...
Hint :Sodium hydroxide is an inorganic compound, it is white solid ionic compound consisting of sodium cation $ N{a^ + } $ and hydroxide anion $ O{H^ - } $ . Sodium hydroxide is a strong base because it dissociates completely in aqueous solution to fo...
The waste solid, bauxite tailings, is removed and aluminium hydroxide is precipitated from the remaining solution of sodium aluminate. This aluminium hydroxide can be converted to aluminium oxide or alumina by calcination. The residue or bauxite tailings, which is mostly iron oxide, is highly ...
