a) The representation is wrong because atoms of potassium and Chlorine are in elemental form instead of ionic form.
b) The unit of potassium chloride dissociates in water to form K⁺ and Cl⁻
What is hydration?
When KCl (potassium chloride) dissolves in water, it dissociates into its constituent ions: K⁺ (potassium cations) and Cl⁻ (chloride anions).
These ions become surrounded by water molecules through a process called hydration, where water molecules surround and separate the ions, allowing them to move freely in the solution.
The potassium and Chlorine atoms do not exit in elemental for as it is written rather they exist in ionic form surrounded by water molecules.
The unit of potassium chloride dissolves in water to K⁺ and Cl⁻. The atoms are represented with charges on the atoms. Potassium atomic which metallic carries positive charge and chlorine atom which is non metal carries negative charge.
