CaCl 2 (solid) Culcium chloride
When calcium chloride ( CaCl₂) is dissolved in water, it undergoes dissociation into its constituent ions, calcium ions (Ca²⁺) and chloride ions (Cl⁻). The dissolution of calcium chloride in water is represented by the following chemical equation: \[ \ text{CaCl}_2 \, (\text{solid}) \rightarrow \text{Ca}^{2+} \, (\text{aq}) + 2\text{Cl}^- \, (\text{aq}) \] In simple terms , each formula unit of calcium chloride breaks down into one calcium ion and two chloride ions when it dissolves in water. This dissociation process is what happens when ionic compounds like calcium chloride are added to water, as water molecules surround and solvate the individual ions, breaking them apart. The resulting solution will contain calcium ions (\( \text{Ca}^{2+} \)) and chloride ions (\( \text{Cl}^- \)) dispersed in the water. This solution can conduct electricity because it contains charged particles (ions) that are free to move. The ability to conduct electricity is a characteristic of solutions con...
