Explanation:
Bayer process is industrial method of the refining of the bauxite to produce alumina which is aluminum oxide.
As alumina is amphoteric in nature, it exhibits a higher solubility at both the extremes of pH range, it is possible to dissolve alumina in low as well as in high pH solutions.
Dissolution of the alumina at high pH is well recognized in Bayer process. Bauxite is digested in very <u>high pH solution (> 13) of alkali</u> like sodium hydroxide at temperature of about 150–250°C and pressure at 20 atm. <u>This is done so that the dissolved alumina is separated from rest of insoluble bauxite minerals. </u>
Answer:
endothermic
Explanation:
endothermic reactions absorb heat from their surroundings, in this reaction the reactants are gas and solid and the products are liquid and gas, implying heat was absorbed to turn a solid to a liquid.
Solution: A Bronsted-Lowry Base is defined as a solution that accept proton/s. hydroxide ion, OH^{-} is a Bronted-Lowry base because it have one negative charge and it can accept 1 proton in the form of H^{+} ion.
Lewis base is defined as an electron rich species that can donate its electron pair to electron deficient species. Here, due to negative charge, hydroxide ion is electron rich and can attack on electron deficient carbon atom or carbocation.
The organic product formed by the reaction of hydroxide ion OH^{-} and carbocation CH_{3}^{+} will be as follows:
OH^{-}+CH_{3}^{+}\rightarrow CH_{3}OH
Thus, the organic product formed will be alcohol.
I want to say Neutrons.
Hope this helps!
Lithium,
Electrons are 3
Protons are 3
Neutrons are 4
