How can we separate naphthalene from sand?
One way is to dissolve the ammonium chloride in water, then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity.
Name a salt which gives white precipitate on ammonium hydroxide solution and is insoluble in excess?
One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.
What does NH4 stand for in chemistry?
The NH4 asked about is the amonium ion, and it's written NH4+ to indicate it has a positive charge (+1). It's a cation. Wikipedia has more information on this chemically significant polyatomic ion, and you'll find that a link to that post is provided below.
What combinations of compounds will make a buffer when mixed?
In order to have an effective buffer, one needs to have a weak acid or a weak base, and the salt (conjugate) of that weak acid or weak base. Examples would be :weak acid/conjugate base: acetic acid/sodium acetateweak base/conjugate acid: ammonia/ammonium chloride
Can a polyatomic ion form chemical bonds.?
A polyatomic ion can form an ionic bond with another ion, and an ionic bond is a type of chemical bond. Some examples: One mole of ammonium ions plus one mole of chloride ions produces one mole of ammonium chloride. NH4+ + Cl- ---> NH4Cl One mole of magnesium ions plus two moles of nitrate ions produces one mole of magnesium nitrate. Mg2+ + 2NO3- ---> Mg(NO3)2
What is the correct name for this compound NH4Cl?
The compound NH4Cl contains one ammonium ion for each chloride ion. Based on the naming rules for ionic compounds, this compound is simply ammonium chloride. Note that NH4 should not be confused with NH3, which is ammonia and is not an ion.
What is one property which is shown by ammonium chloride but not by sodium chloride?
Sublimation is one.
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.
What is the oxidation state of ammonium chloride?
Ammonium chloride doesn't have one oxidation state, there are multiple. But ammonium itslef has an oxidation state of +1 and Chlorine is -1.
What is the formula for ammonium dichloride?
I should point out that ammonium usually combines with chlorine in a one to one ratio, as ammonium chloride (NH4Cl), not ammonium dichloride (NH4Cl2).
What is same between ammonium chloride and Idoine?
Nothing. One is a compound containing ammonium and chloride ions, and one is an element containing only iodine atoms.
What is the oxidation state of chloride?
Ammonium chloride doesn't have one oxidation state, there are multiple. But ammonium itslef has an oxidation state of +1 and Chlorine is -1.
Heat of reaction for ammonium chloride?
heat is one of the reactants.
Why do the sublimation of ammonium chloride in the fume hood?
This question is not grammatically correct. Why does one perform the sublimation of ammonium chloride in a fumehood? Because it creates ammonia and hydrogen chloride vapors, both of which are caustic.
When placed into water will ammonium chloride decrease the temperature of the water?
The dissolution of ammonium chloride, like ammonium nitrate, is an endothermic process, meaning that it will absorb heat. The amount of heat absorbed per mole of ammonium chloride (53.49 g) is 14.7 kJ, enough to lower the temperature of one kilogram of water by 3.5 K.
What is the reaction equation for ammonium chloride and water?
NH4Cl(s) + H2O(l) ----> NH4+(aq) + Cl-(aq) + H3O+(l)Ammonium Chloride + Water----> ammonium ion + chloride ion + hydronium ionAmmonium chloride will only dissolve in water, so water does not react chemically in the chloride's dissociation.each dissolved ammonium chloride molecule results in one molecule of hydrochloric acid and ammonia.NH4Cl + H2O < NH3 + HCl Since NH3 (ammonia) and HCl (hydrochloric acid) are a base and an acid respectively, the reaction equilibrium will favor the left side of the equation.
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.
