I love Chemistry .. only subject im good at .. lol .. right Water acts as an acid.. because well yeah its a proton donor.. also remember the fact its sort of amphoteric.. it can both donate or accept.. at different cases ..

In the production of Aluminum, Sodium Hydroxide is used to separate Aluminum Oxide from the impurities in bauxite ore. The Main impurity in the ore is Iron(3) Oxide. Aluminum Oxide is an amphoteric oxide whilst Iron(3) Oxide us a basic oxide.
Suggest how these two oxides can be separated by the addition of aqueous Sodium Hydroxide.

Yeah because you see.. Aluminum Oxide is Amphoteric..so with the addition of Sodium Hydroxide it would react with aluminium oxide.. leaving behind Iron Oxide.. therefore seperating em.. hmmm hope it helped ..

p.s and yes as iron oxide is basic it would definitely not react with NAOH ..

water if u see it in the product side it will loose one hydrogen. therefore acids tend to loose protons(h+) ions and give it to bases. so u see water behaves like acid as it GIVES or DONATES protons
