Discussion Overview

The discussion revolves around a chemistry problem related to the chemical equation for Barium Chloride Anhydrate and the definition of anhydrate. Participants explore the terminology and chemical formulas involved, as well as clarify concepts related to hydrated and anhydrous compounds.

Discussion Character

  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant seeks help in writing the chemical equation for Barium Chloride Anhydrate and asks for the definition of anhydrate.
  • Another participant questions the use of the term "anhydrate," suggesting "anhydride" might be more appropriate, defining anhydride as a compound formed from others with the removal of water.
  • A third participant clarifies that "anhydrate" refers to the absence of water and emphasizes the importance of distinguishing between hydrated and anhydrous forms of salts, providing an example with copper sulfate.
  • The same participant points out a potential error in the initial formula provided for barium chloride and prompts a reconsideration of the valency of barium and chlorine.
  • The original poster acknowledges the mistake and corrects the formula to BaCl2, expressing gratitude for the assistance.

Areas of Agreement / Disagreement

Participants generally agree on the definitions and distinctions between hydrated and anhydrous compounds, but there is a minor disagreement regarding the terminology of "anhydrate" versus "anhydride." The discussion remains unresolved regarding the broader implications of these terms in different contexts.

Contextual Notes

The discussion includes assumptions about chemical valency and the specific definitions of terms that may vary in different chemical contexts. The initial formula for barium chloride was corrected, but the implications of this correction were not fully explored.

Hello, I need help to these two questions:

How would you write a chemical equation for this compound:
Barium Chloride Anhydrate
What I got so far is BaCl . ?

And what is the definition of Anhydrate?

Any help would be greatly appreciated!

Should it be Anhydride rather than anhydate?

Anhydrede means that a compound is formed from one or more other compounds in a reaction resulting in removal of water.
 
'Anhydrate' is the noun form of the adjective 'anhydrous' , which simply means 'without water'.

It is important to specify, in the case of certain hygroscopic (water absorbing) salts, whether you are talking about the hydrated salt, or the anhydrous salt (also known as the anhydrate). Copper sulfate, for instance hydrates itself with 5 molecules of water per molecule of copper sulfate. So, copper sulfate crystals will have the formula [itex]CuSO_4 \cdot 5H_2O[/itex] when left exposed to atmosphere (and look blue in color). When you heat the crystals sufficiently, you can vaporize and drive out the water leaving behind copper sulfate anhydrate [itex]CuSO_4[/itex], which is white in color.

Likewise with any other inorganic anhydrate. So, in the formula for the anhydrate, there is nothing after the "."

However, you seem to have made a mistake with the formula of barium chloride. What is the valency of Ba ? And Cl ?
 
Oh yeah, my bad, its suppose to be BaCl2 I finally understand it now, Thank you very much guys!
