How do you separate ammonium chloride from a mixture of ammonium chloride and potassium chloride?
Gently heat - ammonium chloride will sublime on a cold solid surface
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 is formed when Barium hydroxide is added to ammonium chloride?
cold
What solutes is most suitable for use in a cold pack ammonium nitrate sodium acetate ammonium chloride urea?
I suppose that the most suitable is the ammonium nitrate - NH4NO3.
Example how a cold pack works?
Ammonium nitrate and water are in separate compartments in the cold pack. To activate the cold pack, you break the compartments in the pack so the ammonium nitrate and water mix. The ammonium nitrate absorbs all of the heat, making the water ice cold.
What type of reaction do you get when you mix ammonium chloride with water endo or exothermic?
good question endothermic. Ammonium chloride dissolves in water and makes it cold.
What happens when ammonium chloride is added to water?
there is no chemical change when ammonium chloride is added to water. NH4Cl + H2O + heat -> products. it also cold when it is dissolved in water.

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.
What is the chemical reaction for Ammonium Chloride and distilled water?
It drops in temperature. It gets cold.
When ammonium chloride mixes with water the solution formed feels cold what type of reaction is this endothermic or exothermic?
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
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.
Why does ammonium nitrate when dissolved in water ina beaker it becomes cold?
god wanted it that way
What is formed when Barium hydroxide is added to ammonium chloride?
cold
How do you separate ammonium chloride and sodium chloride?
The easiest way is to shake the bottles, NaCl wil move easily and NH4Cl wont move very easily when shaken.
What solutes is most suitable for use in a cold pack ammonium nitrate sodium acetate ammonium chloride urea?
I suppose that the most suitable is the ammonium nitrate - NH4NO3.
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.
