Would an acid or an alkali be formed if an oxide were dissolved in water?

When you dissolve an Oxide (e.g. CO2 or SO2) in water you normally make an acid.


Is so2 a base?

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


Is SO2 soluble or insolubel?

soluble:)Just doing that question for chemistry right now:D


What happens when sulphur reacts with water?

Sulphurous acid is formed H2O + SO2 ----> H2SO3


What solution is formed when sulphur dioxide reacts with water in the atmosphere?

SO2 + H2O ==> H2SO3 Sulphurous acid is formed.


When sulfur is burned in air a gaseous oxide is formed If this gas is dissolved a sample of water containing litmus the result will be?

The gaseous oxide formed when sulfur is burned in air is sulfur dioxide (SO2). When sulfur dioxide dissolves in water, it forms sulfurous acid (H2SO3), which is a weak acid. Litmus paper will turn red when dipped in this solution, indicating acidity.


Is sio2 more acidic than so2?

When dissolving CO2 in water it forms a weak acid: H2CO3. SiO2 will not dissolve in water, so it is not acidic (nor base)


What happens when sulphurdioxide is dissolved in water?

They react to form sulphuric acid. 2 SO2 + 2 H2O + O2 → 2 H2SO4


What Dissolved gas presents in acid rain is?

The main dissolved gas present in acid rain is carbon dioxide (CO2). Other gases that can be dissolved in rainwater to form acid rain include sulfur dioxide (SO2) and nitrogen oxides (NOx), which can react with water to form sulfuric acid and nitric acid.


What happens whhen sulphur dioxide is dissolved in water?

When sulfur dioxide is dissolved in water, it forms sulfurous acid (H2SO3). This reaction can lead to the acidification of the water, lowering its pH. Sulfurous acid is a weak acid that can further react to form sulfite ions (SO3^2-) and bisulfite ions (HSO3^-).


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.


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.
