The enthalpy of solution of ammonium chloride is -14.8 kJ/mol. This means that when solid ammonium chloride dissolves in water, it releases 14.8 kJ of heat per mole of solute.
The enthalpy of formation of ammonium chloride is -315.4 kJ/mol.
The standard molar enthalpy of formation for ammonium chloride (NH4Cl) in aqueous solution is -314.4 kJ/mol. This value represents the energy change when 1 mole of NH4Cl is formed from its elements in their standard states at 25°C and 1 atm pressure.
To separate ammonium chloride from a mixture of ammonium chloride and sodium chloride, you can dissolve the mixture in water to form a solution. Then, heat the solution to evaporate the water, leaving behind solid ammonium chloride due to its lower melting point compared to sodium chloride. This process is known as crystallization.
No.If you add ammonium chloride solution to potassium chloride solution all that happens is a solution with all the ions in it - ammonium ions, potassium ions, chloride ions and hydroxide ions.
When ammonium chloride dissolves in water, it absorbs energy from the surroundings, resulting in a positive enthalpy change (endothermic process). The dissolution also leads to an increase in disorder or randomness, resulting in a positive entropy change.
