Question

what does the recrystallization of sodium carbonate gives washing soda mean​

Answer 1

Answer:

Recrystallisation of sodium carbonate gives washing soda. Na 2CO 3 + 10H 2O → Na 2CO 3.10H 2O. This means after sodium carbonate is produced, water is added to it again to purify it and it is allowed to crystalise again , when it forms washing soda.

Answer 2

Answer:recrystallisation means addition of water ..

When you add water to sodium carbonate it forms Na2CO3.10 H2O

Which is the formula for washing soda it's the same but washing soda contains 10 water molecules that is obtained by recrystallisation by adding water to sodium carbonate
