Question

salts x and y are separately dissolved in in H2O samples of solution obtained a separately tested with dilute hydrochloric acid and aqueous sodium hydroxide in two of the test a gaseous product is formed no precipitate is formed in any of the test what are X and y a. X= AgNO3 Y= BaSO4 b. X= BaSO4 Y = Na2CO3 c. X= Na2CO3 Y = NH4Cl d. X=NH4Cl Y = AgNO3

Answer 1

Answer:

16 Salts X and Y are separately dissolved in water. Samples of the solutions obtained are separately tested with dilute hydrochloric acid and with aqueous sodium...

Answer 2

The correct option is d. X = NH4Cl and Y = AgNO3.

• When NH4Cl is dissolved in water, it dissociates into NH4+ and Cl- ions. When AgNO3 is added to this solution, Ag+ ions react with Cl- ions to form a white precipitate of AgCl, which does not happen in this case as no precipitate is formed.
• When aqueous NaOH is added to the same solution, no reaction occurs because NH4+ ion is a weak base and does not react with OH- ions.
• However, when dilute HCl is added to the solution, H+ ions react with NH4+ ions to form NH4Cl and a gas, which is ammonia (NH3), is released.

• When AgNO3 is dissolved in water, it dissociates into Ag+ and NO3- ions.
• When BaSO4 is added to this solution, no reaction occurs because both ions are soluble in water.
• When aqueous NaOH is added to the same solution, no reaction occurs because both ions are already stable.
• However, when dilute HCl is added to the solution, H+ ions react with NO3- ions to form HNO3, and a gas, which is nitrogen dioxide (NO2), is released.

Therefore, the correct option is (D).
