What are the common strong bases in chemistry

Usually refers to a bitter substance whose solution can discolor a specific indicator (e.g., turning litmus blue, phenolphthalein red, etc.), and in the standard case, the pH value is greater than 7. The ions ionized in the aqueous solution are all hydroxide ions, which react with acids to form salts and water. The so-called strong base and weak base are relatively speaking,-- alkali can be completely ionized when dissolved in water, and they belong to strong bases.

For example: caustic soda [sodium hydroxide, Naoh], hydrated lime [calcium hydroxide, Ca(OH)2], barium hydroxide [Ba(OH)2], potassium hydroxide [KOH], cesium hydroxide [CSOH], - active metals correspond to alkalis that are generally strong alkalis.

A broader concept of a base refers to a substance that donates electrons, or a substance that accepts protons.

The alkalinity is derived from the acid-base proton theory, and the strong alkali is the one with a strong ability to accept protons.

Strong alkalis are divided into organic strong bases and inorganic strong bases.

Among the inorganic strong bases, amino compounds (such as potassium amino, sodium amino, etc.) and alkali metal hydrides (Nah, Kh, etc.) are the most alkaline, and then the above hydroxides.

Among the strong organic bases, organometallides are the most alkaline, such as organometallic lithium compounds (such as butyllithium, diisopropyl lithium ammonia, benzyl lithium, etc.), Grignard reagent, alkyl copper lithium, etc. Then there is sodium or potassium alk (such as sodium methoxide, sodium ethoxide, potassium ethanol, sodium tert-butoxide, etc.). The above organic strong alkali alkalinity is stronger than sodium hydroxide.

Guanidine and quaternary ammonium are also strong organic bases, and their alkalinity is comparable to sodium hydroxide.

The common strong bases in middle school chemistry are sodium hydroxide, potassium hydroxide, and barium hydroxide. Magnesium hydroxide and calcium hydroxide are medium-strong bases. Ammonia monohydrate, copper hydroxide, iron hydroxide and other inadmissible substances are weak bases.

Potassium hydroxide, sodium hydroxide, and barium hydroxide are the most common strong bases, as for calcium hydroxide kb =, the ionization degree at room temperature is less than one-fifth of the three strong bases, and cannot be used as a strong base.

Sodium hydroxide, potassium hydroxide.

The above organic strong alkali alkalinity is stronger than sodium hydroxide.

Guanidine and quaternary ammonium are also strong organic bases, and their alkalinity is comparable to sodium hydroxide. Alkali is very corrosive.

2) Inorganic strong alkali: among the inorganic strong alkali, amino compounds (such as amino potassium, amino sodium, etc.), some silicides (such as Mg Si PK greater than 150) and alkali metal hydrides (NaH, Kh, etc.) are the most alkaline, and then the above hydroxides.

Strong alkalis include sodium hydroxide (NaOH), potassium hydroxide (KOH), lithium hydroxide (LiOH), calcium hydroxide (CA (OH)), etc.

Strong alkaline solutions include NAOH (sodium hydroxide), KOH (potassium hydroxide), etc. The aqueous solutions of active metals reacting with water are all strongly alkaline solutions.

Strong base: Base refers to a substance in which all the anions ionized in an aqueous solution are hydroxide ions. The alkali reacts with the acid to form salt and water. The so-called strong base and weak base are relatively speaking,-- alkali can be completely ionized when dissolved in water, and they belong to strong bases.

The alkali metal and some alkaline earth metals correspond to a strong alkali metal. Its solution is in the standard case (concentration of pH 12.

Strong alkaline solutions mainly include the following two situations:

A not-so-dilute solution of a strong alkali (a strong alkali solution is too dilute and its alkalinity may not be strong).

A solution of certain strong bases and weak salts. The weaker the corresponding weak acid, the greater the concentration of the solution, and the stronger the alkalinity of this salt solution. For example, the concentrated solution of Na2S is more alkaline.
