Reaction of Tolens 'reagent with Formalin
Torrens 'reagent was a solution of silver, and its chemical formula was [(AgNH3) 2) Ox]. The reaction equation between Torrens reagent and Formalin is (HCHO +4(Ag(NH_3)_2)OH---(NH_4)_2CO_3 + 4Ag↓+ 6NH_3 +2H_2O\) The reaction would produce a silver mirror phenomenon. This was because the formalin had a reducing property. During the reaction, the formalin was oxided, and the silver ions in the Torrens reagent were reduced to silver, which was deposited on the wall of the glass reaction vessel to form a silver mirror.

A reagent for absorbing nitrogen in the laboratory
The reagents used in the laboratory to absorb nitrogen included saturated salt water (saturated NaCl-solution), acidic solutions such as calcium chloride-acid, sulfuric acid, or sulfuric acid, soda lime, quicklime, silica gel, and a white to light gray powdered solid (composed of a mixture of organic salt, metal dioxide, and surface modifying agent). Among them, saturated salt water absorbs the physical property of the water that is easily dissolved in the water, calcium chlorideabsorbs the chemical property of the octa-ammine calcium chlorideby reacting with the hydrogen gas, acidic solution absorbs the hydrogen gas by reacting with the basic hydrogen gas to produce salt and water, soda lime, quicklime, and silica gel can be used as the basic drying agent to absorb the hydrogen gas, and the hydrogen absorbing agent can absorb the nitrogen and hydrogen gas due to its multi-pore structure and suitable hole diameter.
