Which metals react with the base

to directory mode

Area of ​​Expertise - General Chemistry

In the traditional sense, the term for all compounds that contain hydroxide ions, OH, in aqueous solutions-, release, i.e. reduce the hydrogen ion concentration (alkaline reaction) or form salts through neutralization with acids.

 

Typical bases (also lyes, alkalis) are:

  • water soluble metal hydroxides
  • Anhydrobases that react with water to form hydroxide ions, such as certain metal oxides, ammonia or water-soluble amines

Base metals form particularly strong bases when they dissolve in water. In addition, certain salts of weak acids also have a basic reaction as a result of protolysis.

SN / E competition - SN1 / E1 competition30 min.

chemistryOrganic chemistrysubstitution

This learning unit first describes the mechanistic basics of the competition between eliminations and nucleophilic substitutions. In the following, the different parameters that influence the SN1 / E1 competition are discussed. In the end, the reader should be able to predict the prevailing reaction mechanism of a reaction depending on given parameters or to choose the parameters for a reaction in such a way that a desired mechanism comes to the fore.
