Why does ammonium chloride turn cold when mixed with distilled water?
MichelleBoyster
Ammonium Chloride is slightly acidic salt of NH4+ and Cl-. Though most people erroneously think ammonium chloride is a base (understandably from the "ammonium" part) it is actually an acidic salt.
The positive charge of NH4+ and Cl- essentially forms an ion-ion interaction similar to NaCl. The difference is that for the case of ammonium chloride this ion-ion interaction is strong enough such that it requires a degree of energy to break the ionic interaction. Room temperature distilled water provides a sufficient amount of energy needed to separate and solubilize these charges. If you want to think about the thermodynamics it can be shown thusly:
Free energy of solvation of ammonium chloride is some number dG = +X, indicating an endothermic process.
The heat/energy of room temperature water has a degree of heat or enthalpy of some number dH = -Y which is sufficient to change dG to a negative number: -X making it favorable.
In short, as the dG of the solvation of ammonium chloride becomes negative (more favorable), it is taking heat (enthalpy) from water, making it colder.
Hope this helps.

What is the chemical reaction for Ammonium Chloride and distilled water?
It drops in temperature. It gets cold.
What reactions does ammonium chloride and water produce?
No chemical reactions will happen when ammonium chloride and water is mixed. Water will dissolve ammonium chloride, meaning the ions of ammonium chloride will dissociate, but no chemical reaction involving the creation of new species will occur. The drop in temeperature is due to the fact that the dissolution process for ammonium chloride is endothermic. Changes in temperature therefore are not good indications of chemical reactions.
How do you separate Ammonium chloride from a mixture containing sodium chloride and ammonium chloride?
The secret to separating any mixture is to find a property in which the mixed substances differ. For instance, sodium choride (NaCl)is very soluble in water; whereas, ammonium chloride (NH4Cl) is not. By putting the mixture of NaCl and NH4Cl in water (enough to dissolve all of the NaCl, but not enough to dissolve the NH4Cl), the NaCl will dissolve, and the solid left behind is ammonium chloride.
How do you separate iodine from ammonium chloride?
first you take water in a beaker and put the mixture in it.you will see that ammonium chloride will dissolve in water because it is highly soluble in water and iodine is not so it won't dissolve. However, the solubility of elemental iodine in water can be increased by the addition of potassium iodide.you can then filter out the mixture so the iodine when you filter will stay on the filter paper. you have got your iodine separated.now for ammonium chloride, you can do evaporation or distillation. To get back water you can do distillation and get distilled water.
What color is ammonium chloride?
Ammonium chloride is colorless.Ammonium chloride, as a solid, is white in color. It is highly soluble in water and solutions of ammonium chloride is colourless. The solid form also sublimes on heating.
When heated what happens to ammonium chloride mixed with water in the tube?
nothing happens. it becomes an aqueous solution of ammonium chloride

What solutions are non conductor of electricity water distilled water ammonium chloride sodium chloride hydrochloric acid sodium oxide sulfur dioxide?
sulphur dioxide
What happens to ammonium chloride when it is dissolved in water?
Ammonium chloride, NH4Cl, dissolves in water and dissociates into the ammonium, NH4+, and chloride, Cl-, ions
How do you dissolve ammonium chloride?
Ammonium chloride is very soluble in water.

What is the balanced formula for Ammonium chloride and water?
Your question isn't clear - there is no reaction between ammonium chloride and water beyond dissolution. Do you mean the formula for hydrated ammonium chloride - NH4Cl.xH2O? ?
How does ammonium chloride break up with water evaporation?
Ammonium chloride is dissociated in water; after water evaporation the solid NH4Cl is reformed.

How can you separate a mixture of naphthalene and ammonium chloride?
One way is to slurry the solid mixture with water. The ammonium chloride will dissolve and the naphthalene will not. Ammonium chloride can then be recovered by evaporating the water solution of it that is formed.
