If a few drops of water are added to a mixture of solid silver nitrate and powdered magnesium the mixture bursts into flames. The water dissolves the silver nitrate to make a highly concentrated solution. An exothermic displacement reaction occurs which ignites any excess magnesium.
The ion does form a protective, water insoluble zinc hydroxide (Zn(OH) 2) layer with dissolved hydroxide ions, according to the following reaction mechanism: Zn 2+ + 2OH - 2 (s). Zinc reacts with H+ ions, according to the following reaction mechanism: Zn(s) + 2H + 2+ (aq) + H 2 (g).This reaction releases hydrogen, which reacts with oxygen explosively.inc is naturally present in water. The average zinc concentration in seawater is 0.6-5 ppb. Rivers generally contain between 5 and 10 ppb zinc. Algae contain 20-700 ppm, sea fish and shells contain 3-25 ppm, oysters contain 100-900 ppm and lobsters contain 7-50 ppm.
