What are the final products when CaCl2 x 2H20 are heated strongly?
The hydrated CaCl2 is just dehydrated.
CaCl2.2H2O + heat --> CaCl2(s) + 2H2O(g)
So, the result is just Ca and H2O?
No, the result is CaCl2 and H2O. The CaCl2 does not decompose.
Sorry, I understand now. Thanks.
What about write the reaction for the dehydration of CuSO4 . XH20?
To determine the final products when CaCl2 x 2H2O (calcium chloride dihydrate) is heated strongly, we can analyze the chemical equation for the decomposition reaction:
CaCl2 x 2H2O(s) → CaCl2(s) + 2H2O(g)
When heated strongly, calcium chloride dihydrate decomposes into calcium chloride (CaCl2) and water (H2O) in the gaseous state. This can be understood by breaking down the chemical formula of calcium chloride dihydrate, which consists of one calcium ion (Ca2+) and two chloride ions (Cl-) combined with two water molecules (2H2O).
By applying heat, the crystal structure of calcium chloride dihydrate breaks down, and the water molecules are released in the form of steam or water vapor (H2O(g)), while the remaining solid calcium chloride (CaCl2(s)) is left behind.
Overall, the final products when CaCl2 x 2H2O is heated strongly are calcium chloride (CaCl2) in its solid form and water vapor (H2O(g)).
