[580] [Ag^{+}] × [NH_{3}]^2 / [Ag(NH_{3})_{2}^{+}] = 1 / 10^7.

[581] Methylene CH_{2}, itself, has never been isolated, but

derivatives of it are known, such as the cyanides, C(NH), C(NK)

(see pp. 66, 237).

[582] Potassium cyanide, =C(NK), is a powerful reducing agent (see

p. 89).

[583] Pp. 65, 66.
