Write the reaction equation: Br2 → HBr → NaBr → AgBr → Ag → Ag2O → AgNO3 → Ag
August 28, 2021 | education|
Let us write down the reaction equations for inorganic substances:
Br2 + H2 = 2HBr – the reaction of the compound, hydrogen bromide is released;
HBr + NaOH = NaBr + H2O – ion exchange, sodium bromide obtained;
NaBr + AgNO3 = NaNO3 + AgBr – ion exchange, silver brolmide was formed;
AgBr + Sn = Ag + SnBr – substitutions, silver is released;
4Ag + O2 = 2Ag2O – oxidation of silver, silver oxide was released (1);
Ag2O + 2HNO3 = 2AgNO3 + H2O – ion exchange, silver nitrate was formed;
AgNO3 – solution electrolysis.
AgNO3 = Ag + + NO3-
K- | Ag + + e = Ag;
A + | 2H2O – 4e = O2 + 4H +
Total electrolysis equation:
4AgNO3 + 2H2O = 2Ag + 4HNO3 + O2
The given reaction equations show the relationship between non-metals and metals.
