Question

Which of the following salt can be used as a cleaning agent for domestic purposes?

• A. X = NaOH, Y = H₂O and Z is washing soda
• B. X = Na₂CO₃, Y = NH₄Cl and Z = Baking soda
• C. X = NH₄Cl , Y = NaHCO₃ and Z = Washing soda
• D. X = NaHCO₃, Y = NH₄Cl and Z = Na₂CO₃.10H₂O

Answer 1

The correct option is A

X = NaOH, Y = H₂O and Z is washing soda

Washing soda (chemical name: sodium carbonate) can be used as a cleaning agent for domestic purposes. In the laundry room, the high alkalinity of washing soda allows it to act as a solvent in removing a wide range of stains. For home laundry, washing soda can be dissolved in water to create a presoaking solution for tough stains like grease, blood, tea and coffee stains.
