What salts do ammonium salts react with? Junior high school chemistry, please list a few more! Tha

Ammonium salt. The products of ammonia reaction with acids are ionic compounds composed of ammonium ions and acid ions.

Can react with alkalis.

nh4+oh-

NH3 H2O (heated).

It can be used to test NH4+

It can also be used to make ammonia.

Depending on the ions contained in your salts, hydroxide ions can react with ammonium salts.

Hopefully, thank you.

Ammonium salts: 1) NH4Cl

It can react with agno3.

2)(NH4)2SO4 can react with BACl2, BA(NO3)2, and AGNO3.

3) (NH4)2CO3 can be compared with BACl2, BA(NO3)2, CaCl2, Ca(NO3)2, ZNCL2, ZN(NO3)2,

mgcl2、mg（no3）2...

Idea: If the ammonium salt (NH4+) is completely soluble in water, then the reaction type between the ammonium salt and the salt is metathesis, and the product of metathesis requires at least water, precipitation, and carbon dioxide.

One of the three, and the salt that reacts with the ammonium salt, must be soluble. If the product contains water, then the reaction with ammonium salt needs to have OH- (base), which is combined with NH4 to form NH3·H2O

ammonia), not salt. If the product has gas (in this case, NH3 ammonia), then you will learn in high school that ammonia gas will be released when it is mixed (heated) with alkali, which is not in line with the topic. The remaining product can only be precipitated, because the ammonium salt is fully soluble, so it can only be the cation of the salt that reacts with the ammonium salt.

Anions with ammonium salts.

Combine to form precipitates, for example, as in (1), NH4Cl and Agno3, the two salts are fully dissolved, and Agno3 is ag+ (silver ion.

It can be combined with Cl- (chloride ion) in NH4Cl to form precipitated AGCL, then it can react. 】

Hope for academic progress!!

In general, ammonium salts react with alkali to produce ammonia gas, so ammonium salts that do not react with alkali are rare. Here are some of the ammonium salts that do not react with alkalis:

Ammonium chloride: Ammonium chloride is a common ammonium salt that does not react with alkalis.

Ammonium sulfate: Ammonium sulfate also does not react with alkali, but will decompose at high temperatures to produce ammonia and sulfuric acid in the first rock.

Ammonium nitrate: Ammonium nitrate does not react with alkali at room temperature, but it will decompose at high temperature to produce nitrogen oxide and water.

It is important to note that although the above ammonium salts do not react with alkalis, they can still react with acids.

The chemical reaction equation for the reaction of ammonium salt and base is: 2nHCl + Ca(OH) = 2nH +CaCl +2HO.

The ionic equation is: NH HCO = NH CO Ho (all conditions are heated).

Ammonium salts are ionic compounds, all of which are white crystals (NH4MNO4 is purple-black), soluble in water, and absorb heat when dissolved in water. When cold, the two are recombined into ammonium chloride, which is similar to the phenomenon of "sublimation", but different from the sublimation of I2. NH4HCO3 is completely vaporized when heated, and a phenomenon similar to "sublimation" also occurs.

The products of thermal decomposition of ammonium salt should be analyzed according to the specific situation, which is generally related to many factors such as temperature and oxidation of acid groups in ammonium salt.

No, it can react with alkali under certain conditions.

Alkaline substances can be alkalis, or they can be strong alkalis and weak salts. For example, Na2CO3 solution, NaHCO3 solution, etc. are strong alkaline solutions, but it cannot be combined with ammonium salts.

React. Ammonium salts and alkalis can undergo metathesis reactions.

Ammonia is released under heating conditions, which is a common method for producing ammonia in the laboratory.

1. Ammonium chloride solution mixed with sodium hydroxide solution: chemical equation: NH Cl + NaOH = NaCl + NH ·h O; Ionic equation: NH + OH = NH·HO.

2. Heating the mixed solution of ammonium chloride and sodium hydroxide: chemical equation: NH Cl + NaOH = NaCl + NH H O; Ionic equation: NH + OH = NH·HO.

3. Operation and phenomenon: take an appropriate amount of solution in the test tube, add sodium hydroxide solution, heat, and place a moist red litmus test paper at the mouth of the test tube, if the test paper turns blue, it means that there is NH+ in the solution. Ionic Equation:

nh ₄+oh-=nh ₃↑h₂o。

No heating: NH4Cl+NaOH=NH3·H2O+NaClNH4+ +OH-=NH3·H2O

Heating: NH4Cl+NaOH=δ=NH3 +H2O+NaClNH4+ +OH-=δ=NH3 +H2O Operation: Take a small amount of the solution to be tested in the test tube, add excess NaOH solution dropwise and heat slightly, and place the moistened red litmus test paper at the mouth of the test tube.

Phenomenon: Red litmus paper turns blue.

Chemical Reaction Equation for Ammonium Salt and Base Reaction:

Check whether a solution is an ammonium salt solution.

Operation and phenomenon: take an appropriate amount of solution into the test tube, add sodium hydroxide solution, heat, and place a moist red litmus test paper at the mouth of the test tube, if the test paper turns blue, it means that there is NH4+ in the solution

Some insoluble alkalis, such as Ca(OH)2 and Mg(OH)2, can react with ammonium to form ammonia.

Alkaline substances, as long as they are more alkaline, can also react with ammonium, such as Naalo2, Na2Zno2, etc., which can be regarded as a complete double hydrolysis reaction between ammonium and anion.

Chemical Reaction Equation for Ammonium Salt and Base Reaction:

nh₄cl + ca(oh)₂=2nh₃↑+cacl₂ +2h₂o

nh₄no₃+ ca(oh)₂=2nh₃↑+ca(no₃)₂2h₂o
