Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Washing soda is sodium carbonate decahydrate, represented as Na\(_2\)CO\(_3\)·10H\(_2\)O. This indicates that washing soda contains 10 water molecules.
Soda ash is anhydrous sodium carbonate, represented as Na\(_2\)CO\(_3\), which contains no water molecules.
Thus, the number of water molecules in washing soda is 10, and in soda ash is 0.
Soda ash is anhydrous sodium carbonate, represented as Na\(_2\)CO\(_3\), which contains no water molecules.
Thus, the number of water molecules in washing soda is 10, and in soda ash is 0.
