Question

Give two chemical properties that are common to both carbon (iv) oxide and sulphur (iv) oxide

Answer 1

Answer:

i) both are acidic in nature

ii) both react with NaOH to form their respective salts

Explanation:

2NaOH + CO2 -> Na2CO3 + H2O

2NaOH + SO2 -> Na2SO3 + H2O

Answer 2

Carbon (iv) oxide and sulfur (iv) oxide are chemically formulated as CO$_{2}$ and SO$_{2}$ respectively.

The chemical properties that are common to both CO$_{2}$ and SO$_{2}$ are:

• Both of the compounds are acidic.
• Since both of them are acidic, hence on reacting with litmus paper the blue litmus paper turns into red, indicating both of them are acids.
• Both the compounds react with water,

=> CO$_{2}$ + H$_{2}$O -----> H$_{2}$CO3.

=> SO$_{2}$ + H$_{2}$O ------> H$_{2}$SO3.

• Both compounds react with sodium hydroxide,

=> 2NaOH + CO2 ----> Na2CO3 + H2O.  

=> 2NaOH + SO2 -----> Na2SO3 + H2O.

• However, Carbon dioxide and Sulfur dioxide can be distinguished by using acidified dichromate paper test.
• Carbon dioxide and Sulfur dioxide can also be distinguished using Zinc nitroprusside paste in water.
