When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
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.

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.
Why does ammonium nitrate dissolve in water?
Ammonium nitrate dissolves in water because it is a highly water-soluble salt. When it comes into contact with water, the polar water molecules interact with the charged ions in ammonium nitrate, causing it to dissociate into ammonium and nitrate ions, which become uniformly distributed in the water solution.
Why does ammonium nitrate when dissolved in water ina beaker it becomes cold?
When ammonium nitrate dissolves in water, it undergoes a process called dissolution, which is an endothermic reaction. This means that energy is absorbed from the surroundings, causing the temperature to decrease or the system to become colder. The heat required for the dissolution to occur is taken from the surroundings, resulting in a cooling effect.
What is Ammonium iodide plus water?
When ammonium iodide is added to water, it will dissociate into ammonium ions (NH4+) and iodide ions (I-). This results in a colorless solution that may produce an ammonia odor due to the presence of ammonium ions.
Is ammonium ion a reducing or oxidising agent?
Ammonium ion (NH4+) is a reducing agent because it can donate electrons to other species, causing them to be reduced. In this process, the ammonium ion itself becomes oxidized.
Why ammonium chloride in water becomes cold?
When ammonium chloride dissolves in water, it undergoes an endothermic reaction, meaning it absorbs heat from the surroundings. This absorption of heat causes the temperature of the solution to decrease, and as a result, the solution feels cold to the touch.
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.
When heated what happens to ammonium chloride mixed with water in the tube?
When heated, ammonium chloride mixed with water in the tube will undergo decomposition to produce ammonia gas, hydrogen chloride gas, and water vapor. This reaction is endothermic, meaning it absorbs heat from the surroundings. The ammonia gas can be identified by its pungent smell.
What happens when ammonium sulfate is added to a water?
When ammonium sulfate is added to water, it dissolves and dissociates into ammonium ions (NH4+) and sulfate ions (SO4^2-). This process is exothermic, meaning it releases heat. The resulting solution becomes acidic due to the formation of ammonium ions, which can react with water to form ammonium hydroxide (NH4OH) and contribute to the acidity.
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
What happens to the temperature when barium hydroxide react with ammonium chloride?
When barium hydroxide reacts with ammonium chloride, the reaction is exothermic, which means it releases heat. This causes the temperature to increase in the surroundings where the reaction is taking place.

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.
Could NH4 be a gas?
NH4 is an ion. It does not exist under normal conditions. It may exist in combined state as Ammonium Chloride NH4Cl (which is a sublimates and exists only in solid and gaseous state), Ammonium Nitrate NH4NO3, Ammonium Sulphate (NH4)2SO4 which may exist in gaseous state at high temperatures. In case you are talking about Ammonia which is NH3, then yes,it is a gas under normal conditions but becomes a liquid on bubbling through water. (Ammonia solution of varying concentrations), much like Hydrogen Chloride, which on bubbling through water, forms, Hydrochloric acid in varying concentrations.
Why does ammonium nitrate dissolve in water?
Ammonium nitrate dissolves in water because it is a highly water-soluble salt. When it comes into contact with water, the polar water molecules interact with the charged ions in ammonium nitrate, causing it to dissociate into ammonium and nitrate ions, which become uniformly distributed in the water solution.
How does water become saline?
Water becomes saline when it dissolves minerals and salts as it flows through rocks and soil. These minerals include sodium, chloride, magnesium, and calcium, which contribute to the salinity of water. Additionally, water bodies can become saline due to evaporation, leaving behind dissolved salts.
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-
