Give equations for the following conversions:
A. Ammonium hydroxide to ammonium nitrate.
B. Potassium hydroxide to Potassium sulphate.
C. Copper hydroxide to Copper sulphate.
D. Zinc to Zinc nitrate.
Answers
Explanation:
1.NH4NO3 is ammonium nitrate. NH4OH is ammonium hydroxide, which by convention is how ammonia in aqueous solution is denoted since each molecule of NH3 associates itself with a molecule of H2O to form NH4OH before it dissociates into NH4+ and OH- ions.)
2.Potassium hydroxide reacts with sulfuric acid. Potassium sulfate and water are formed in the reaction. This means that: the reactants are potassium hydroxide and sulfuric acid.
3.Copper(II) hydroxide can be produced by adding a sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO. 5H2O). The precipitate produced in this manner, however, often contains water and an appreciable amount of sodium hydroxide impurity.
4.Zinc nitrate is usually prepared by dissolving zinc in nitric acid, this reaction is concentration dependent, with a reaction in concentrated acid also forming ammonium nitrate: Zn + 2 HNO3 (diluted) → Zn(NO3)2 + H. 4 Zn + 10 HNO3 (concentrated) → 4 Zn(NO3)2 + NH4NO3 + 3 H2O.
