WitrynaAcids will react with reactive metals, such as magnesium and zinc, to make a salt and hydrogen. acid + metal → salt + hydrogen. hydrochloric acid + zinc → zinc chloride + … WitrynaIn this colorimetric method, use for drinking water, wastewater and seawater, nitrate is reduced to nitrite with hydrazine sulfate. The diazonium reagents then react with the nitrite to produce a red color. The intensity of the color is proportional to the original amount of nitrate and nitrite present in the sample.

Iron(II) nitrate is the nitrate salt of iron(II). It is commonly encountered as the green hexahydrate, Fe(NO3)2·6H2O, which is a metal aquo complex, however it is not commercially available unlike iron(III) nitrate due to its instability to air. The salt is soluble in water serves as a ready source of ferrous ions. Witryna23 wrz 2024 · 7.5: Solution Stoichiometry.
