Individual Reactions

(H₂S⁺ • ) +  = (H₂S⁺ • 2)

By formula: (H₂S⁺ • H₂S) + H₂S = (H₂S⁺ • 2H₂S)

H₂S⁺ +  = (H₂S⁺ • )

By formula: H₂S⁺ + H₂S = (H₂S⁺ • H₂S)

(H₂S⁺ • 2) +  = (H₂S⁺ • 3)

By formula: (H₂S⁺ • 2H₂S) + H₂S = (H₂S⁺ • 3H₂S)

(H₂S⁺ • 3) +  = (H₂S⁺ • 4)

By formula: (H₂S⁺ • 3H₂S) + H₂S = (H₂S⁺ • 4H₂S)

(H₂S⁺ • 4) +  = (H₂S⁺ • 5)

By formula: (H₂S⁺ • 4H₂S) + H₂S = (H₂S⁺ • 5H₂S)
