# How effectively bound Na2CO3 and BaCL2 water

How fast does $\ce{BaCl2}$ bind water from its surroundings, becoming a hydrate, compared with same process with $\ce{Na2CO3}$?

• That's an awfully specific question… I am wondering what you are trying to achieve. What's the context? – F'x Oct 22 '13 at 15:07
• How fast BaCl2 absorb again water and becoming hydrate after vaporazing the water, compared to Na2CO3 – Petr Oct 22 '13 at 18:03
