Ammonium chlorideAmmonium chloride is a very inexpensive and readily available reagent, and efficiently catalyzes the thia-Michael addition reaction of thiols to different α-enone Michael acceptors in water. Reasonable to good yields of the desired products were obtained in most cases.doi:10.1016/j....
This is a rare example of spontaneous reaction of solids [though both materials are hygroscopic and presumably have a surface water film in which the Editor imagines reaction to start]. See Ammonium salts, above Maize husks, Sodium nitrate See Sodium nitrate: Maize husks, etc. Metal amido...
Submit Dissolution of ammonium chloride in water is an endothermic reaction, yet it is a spontaneous process. This is due to the fact that AΔH is +ve,ΔS is −ve BΔH is −ve,ΔS is +ve CΔH is +ve,ΔS is +veandΔH<TΔS DΔH is +veandΔH>TΔSSubmit...
corrosion of copper but no corrosion of pig iron. Ammonium chloride can be obtained from the neutralization reaction of ammonia and hydrogen chloride or ammonia and hydrochloric acid (reaction equation: NH3 + HCl → NH4Cl). When heated, it will decompose into hydrogen chloride and ammonia ...
Ammonium in solution is in equilibrium with ammonia, which acts like a Brønsted-Lowry base, according to the reaction: H30+ + NH3 < - > NH4+ + H2O. The NH3gas crosses the cell membranes, and once within the cytosol regenerates NH4+, thereby reducing the concentration...
Freely soluble in water. IDENTIFICATION A. It gives the reactions of chlorides. B. 10 ml of solution gives the reaction of ammonium salts. TESTS Solution S A 10% solution: Appearance of solution: Solution is clear and colorless. Acidity or alkalinity: To 10 ml of solution S add 0.05 ml ...

Catalysis: Tetrabutyl ammonium chloride is commonly used as a phase transfer catalyst in organic synthesis. Its purpose in this field involves facilitating the transfer of reactants between immiscible phases, thereby increasing reaction rates and improving yields. The mechanism of action in catalysis inv...
