When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.

What is Ammonium iodide plus water?

It does not react in water, so it becomes Diluted Ammonium iodide


Why does ammonium chloride turn cold when mixed with distilled water?

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.


A chlorine atom becomes a chloride ion when it is?

When it gains an electron. It then becomes a negative ion.

How do you separate ammonium chloride from lead chloride?

They are simply separated by Sublimation process , heat the mixture in an open container and put a large inverted funnel on container the Ammonium chloride becomes sublimed and its white crystals becomes deposited on the walls of funnel leaving the Lead chloride in container.


What happens to the temperature when barium hydroxide react with ammonium chloride?

I know that it drops, but I don't know what the temperature becomes. It is quite cold though.


What to mix to make sodium chloride?

When the sodium chloride dissolves in water, it becomes an aqueous solution. As a related sidenote, when sodium chloride reacts with water, it becomes hydrochloric acid + sodium hydroxide, which can be illustrated by the balanced equation: H2O + NaCl <-> HCl + NaOH

Can carbon steel be used as pump material in Ammonium Chloride services?

As the pumps are used to transfer the liquid from one place to another place,not solid. ammonium chloride is a crystalline solid. if we make solution of ammonium chloride with the water it becomes slightly acidic,when this acidic solution passes through the carbon steel make pump,it will corrode the pump because the carbon steel is not resistant to corrosion. also the oxide layer form is dissolved by the solution which causes the rate of corosion increases and ultimately the equipment damaged.

What happens when CHI gas dissolves in water?

CHI doesn't exist. Perhaps you meant HCl (hydrogen chloride gas). If so, when placed in water, it becomes hydrochloric acid which ionizes into H+ and Cl-
