Parts and what they mean

• V⁴⁺: blue (V⁴⁺: नीला) — V⁴⁺ = 3d¹. Blue (as VO²⁺ in water).
• V³⁺: green (V³⁺: हरा) — V³⁺ = 3d². Green.
• Mn²⁺: pale pink (Mn²⁺: हल्का गुलाबी) — Mn²⁺ = 3d⁵. Very pale pink.
• Fe³⁺: yellow (Fe³⁺: पीला) — Fe³⁺ = 3d⁵. Yellow.
• Co²⁺: pink (Co²⁺: गुलाबी) — Co²⁺ = 3d⁷. Pink.
• Ni²⁺: green (Ni²⁺: हरा) — Ni²⁺ = 3d⁸. Green.
• Cu²⁺: blue (Cu²⁺: नीला) — Cu²⁺ = 3d⁹. Blue.
• d⁰ and d¹⁰ ions are colourless (d⁰ और d¹⁰ आयन रंगहीन) — Sc³⁺, Ti⁴⁺ (d⁰) and Zn²⁺, Cu⁺ (d¹⁰) have no d–d transition, so they are colourless (Table 4.8).
