Write the dissociation equation for calcium chloride. Include a diagram of the resulting solution.
Diagram of the solution? We can't do that on this forum.
The dissociation equation for calcium chloride is as follows:
CaCl2(s) → Ca2+(aq) + 2Cl-(aq)
To understand this equation, let's break it down step by step:
1. Calcium chloride (CaCl2) is initially in solid state. It consists of Ca2+ ions and 2Cl- ions, held together by ionic bonds.
2. When calcium chloride is dissolved in water (H2O), the ionic compound dissociates or breaks apart into its constituent ions.
3. The positive calcium ion (Ca2+) and the negative chloride ions (Cl-) are released into the solution, creating an aqueous solution.
Now, let's visualize the resulting solution:
[Ca2+]
↑
|
H2O + CaCl2 |
|
↓
[Cl-]
In the resulting solution, the calcium ions (Ca2+) and chloride ions (Cl-) are dispersed throughout the water molecules (H2O). The Ca2+ ions will be attracted to the partially negatively charged oxygen atoms in the water molecules, and the Cl- ions will be attracted to the partially positively charged hydrogen atoms in the water molecules.
