Parts and what they mean

• Sodium ion Na⁺ (सोडियम आयन Na⁺) — Positive ion: water turns its negative oxygen end towards it.
• Chloride ion Cl⁻ (क्लोराइड आयन Cl⁻) — Negative ion: water turns its positive hydrogen end towards it.
• Water around Na⁺ (oxygen inward) (Na⁺ के चारों ओर जल (ऑक्सीजन अंदर)) — Oxygen carries partial negative charge (δ−).
• Water around Cl⁻ (hydrogen inward) (Cl⁻ के चारों ओर जल (हाइड्रोजन अंदर)) — Hydrogen carries partial positive charge (δ+).
• Ion–dipole attraction (आयन–द्विध्रुव आकर्षण) — Polar solvent (water) dissolves ionic solids — “like dissolves like”. Non-polar benzene cannot do this.
