Why does the reaction of silver nitrate and magnesium produce a black solid

This phenomenon is normal. Silver nitrate.

Reacting with magnesium, it is magnesium that replaces silver, so there will be silver generation, because the silver produced is not uniform, and part of it is attached to magnesium, the small particles of silver are black, not the silvery-white that we usually see. So those black solids are the silver particles that are generated. After a period of reaction, the silver nitrate is depleted and magnesium nitrate is formed.

solution, in a neutral solution, magnesium ions are easily hydrolyzed to form white magnesium hydroxide.

Precipitation. When it is mixed with fine particles of black silver, it appears gray overall. So the gray substance is a mixture of black silver particles and a precipitate of white magnesium hydroxide.

Summary. According to the type of reactants and products, it can be divided into four categories: chemical reaction reaction, decomposition reaction, displacement reaction and metathesis reaction can be divided into the following according to the gain and loss of electrons

redox reactions, non-redox reactions; Redox reactions include: autoredox, isomerization of the reactive reaction between the reducing agent and the oxidant: (a b):

Compounds are compounds that form structural restructurings without changing the chemical composition. Chemical synthesis: The chemical reaction is abbreviated as:

A + B = C: Two or more elements or compounds to form a complex product. (i.e., a reaction in which two or more substances produce a new substance.)

Chemical decomposition: The decomposition reaction is abbreviated as: a = b + c:

The decomposition of a compound into constituent elements or small molecules (i.e., the reverse reaction of the chemical reaction. It refers to the reaction in which a compound is broken down into two or more simpler elements or compounds under specific conditions. ）

Do magnesium sulfate and silver nitrate react.

Hello dear, please wait a moment.

Hello dear, magnesium sulfate and silver nitrate will react, magnesium will replace the silver in silver nitrate, and the replacement reaction will occur, and the reaction will form magnesium nitrate and silver element.

According to the type of reactants and products, it can be divided into four categories: chemical reaction, decomposition reaction, displacement reaction, and metathesis reaction, which can be divided into redox reaction and non-redox reaction according to electron gain and loss; Redox reactions include:

Autoredox, reactive isomerization of reducing agent and oxidant: (a b): A compound is the formation of a structural recombination without changing the chemical composition.

Chemical synthesis: The chemical synthesis reaction is abbreviated as: A + B = C:

Two or more elements or compounds form a complex product. (i.e., a reaction in which two or more substances produce a new substance.) Chemical decomposition:

Let the CuSO4 generated by decomposition be Xmol and the AG generated by decomposition be Ymol.

then 160x+108y=

by the first. 2. The three equations show that O2 is left, and the generated N(NO2)=ymol, N(O2)=, and the three equations reflect O2

then O2 remains
