2 AgNO3 (aq) + CH2O (aq) + 3 NaOH (aq) → 2 Ag (s) + HCOONa (aq) + 2 NaNO3 (aq) + 2 H2O (l)
This is an oxidation-reduction (redox) reaction:
C0 - 2 e- → CII (oxidation)
2 AgI + 2 e- → 2 Ag0 (reduction)
CH2O is a reducing agent, AgNO3 is an oxidizing agent.
This is a precipitation reaction: Ag is the formed precipitate.
Reactants:
- AgNO3 – Silver(I) nitrate, Silver nitrate
- CH2O – Formaldehyde , Methanal
- Other names: Methyl aldehyde , Methylene glycol , Methylene oxide
- Appearance: Colorless gas ; Colourless gas with pungent odour ; Colourless liquid with pungent odour ; Nearly colorless gas with a pungent, suffocating odor. [Note: Often used in an aqueous solution (see specific listing for Formalin).]
