Title: If Na goes into Borates compound does it lost its alkali feature?
Post by: metallurgy on June 23, 2020, 09:37:57 AM

I mean if Sodium goes into Sodiumtetraborates, does it loss its own alkali attribute?

Boric acid is a weak acid, so the Sodium Salt will be still alkaline.

If we talk by the metallurgy view point (blast furnace impacts etc.) alkali metals and alkaline metals are different things.

So will it be alkali or alkaline in an sodiumtetraborats?

The word alkaline metal is not existing. On one hand there are alkali metals like sodium, potassium and others. On the other hand there are alkaline  substances  like salts from alkali metal or earth alkali  metal like Calcium , Magnesium, and others and weak acids like boric acid, Hydroxides. Carbonates and also Oxides.

To further confuse things there are alkaline earth metals - second group of the periodic table.

Yes this will confuse, in my language we call it Earth alkali metal = Erdalkalimetalle. The english translation sounds like alkalische Erdmetalle = alkaline earth metals.

Do they (alkaline earth metals - second group) generates scaffold inside the blast furnace? I mean do they still shows their own alkaline /alkali attributes if they are contained in Sodiumtetraborates,Potassiumtetraborates or Calciumtetraborates?

Again, the alkaline, neutral or acidic behaviour is given in combination of the partner of th metal.

Example sodium combined with chloride coming from strong hydrochloric acid as we know is neutral.
If combined with boric acid its alkaline and if the half of sulfuric acid is neutalize,d, we have sodium hydogensulfate which is still acidic.
