When dissolving CO2 in water it forms a weak acid: H2CO3.

SiO2 will not dissolve in water, so it is not acidic (nor base)

Why so3 is more acidic than so2?

SO3 is more acidic than SO2 because the sulfur atom in SO3 has a higher oxidation state (+6) compared to SO2 (+4). This leads to a more polar bond between sulfur and oxygen, making it easier for SO3 to donate a proton and form a stronger acid. Additionally, SO3 forms a stable conjugate base (HSO4-) compared to SO2 (HSO3-), further enhancing its acidic nature.


Why is so2 a powerful reducing agent in alkaline medium than in acidic medim?

SO2 acts as a reducing agent because of the liberation of nescent hydrogen in the presence of moisture;SO2 + 2H2O ---------- H2SO4 +2HAlkali neutralises the acid (H2SO4) and shifts the equilibrium in the forward direction producing more nascent hydrogen.however,in acidic medium,the equilibrium is suppressed resulting in a lesser amount of nascant hydrogen.consequently,SO2 is better reducing agent in alkaline medium than in the acidic medium.....if you are satisfy with my answer than...wel done me...hahahah....otherwise abuse me...i will be satisfy with your abusingPosted by Sachin Bagga(student), 1 minute ago


Is SO2 acidic or basic?

SO2 is acidic. When dissolved in water, it forms sulfurous acid, which can donate a hydrogen ion, making the solution acidic.


Which is more acidic so2 or so3?

so3 Because it has a higher oxidative state than So2


Is so2 a strong base?

No, SO2 (sulfur dioxide) is not a base. It is an acidic gas that can react with water to form sulfurous acid (H2SO3), making it an acidifying compound.


Is so2 neutral?

No sulphur dioxide is not neutral. It is acidic. It is one of the acidic gasses.


Is so2 a base?

No, when bubbled through water it produces sulfurous acid H2SO3.


Is SO2 acid?

Yes,it is an acid.It an acidic gas.


Will pH fluctuate in water?

Yes, because water absorb from atmosphere gases wit acidic potential (CO2, NO2, SO2, etc.) and become more acidic.


Is the pH of a water sample lowered more when equal amounts of CO2 or SO2 are introduced?

The pH of a water sample is typically lowered more when equal amounts of SO2 are introduced compared to CO2. This is because SO2 readily reacts with water to form sulfurous acid, which is a stronger acid than the carbonic acid formed when CO2 dissolves in water.


What does the nature of non metallic oxides?

Non-metallic oxides are typically acidic in nature. They tend to react with water to form acidic solutions, which can corrode metals and have a sour taste. Examples include carbon dioxide (CO2) and sulfur dioxide (SO2).


Is SO an acid or base?

There is no compound as SO. SO2 and SO3 are acidic
