Explain using examples what is an amphoteric oxide. What kind of conditions would I want if I wanted to get as much CO2 to go into a soda as I could? a) What was the purpose of washing the filtered calcium carbonate (CaCO_3) with a small amount of ethanol? b) What is the eff...
A base is a substance that produces hydroxide {eq}OH^- {/eq} ions when dissolved in water. For example, {eq}NaOH,\; KOH,\; LiOH \; and\; CaO\; etc. {/eq}. Answer and Explanation:1 An amphoteric substance is a substance that can chemically act both as an acid as well as ...
Is Fe2O3 acidic or basic? Ferric oxide, also known as iron(III) oxide, is an amphoteric oxide of iron with the chemical formula Fe2O3. It can be noted that oxides of iron, aluminium, and tin, are all amphoteric chemical species – they exhibitboth acidic and basic qualities. How man...
Aluminium hydroxide, Al(OH)3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium ...
it is an amphoteric oxide. Pure Zinc oxide is obtained by calcining zinc ore or burning zinc strips in air. The Zinc oxide crystal is a hexagonal crystal system, with a lattice constant of α=3.25×10-10m and c=5.20×10-10m. Zinc oxide crystals or polycrystals that meet the stoichiometric...

Turns out, it’s really not as simple as it seems. NaHCO3, aka sodium bicarbonate, aka baking soda, is a chemical salt that occurs in its natural form as the mineral nahcolite. NaHCO3is an amphoteric compound, which means it may react as an acid as well as a base, although in aque...
is that amphiprotic is being able to both donate and accept a proton, and thus being able to react both as an acid and a base; amphoteric while amphoteric is having the characteristics of both an acid and a base, and capable of reacting as either; amphiprotic. amphiprotic English (wikiped...
