Description

Sodium hydroxide (Latin Natrii hydroxidum; other names — the caustic soda, a caustic soda, caustic rubbed, caustic alkali) — the most widespread alkali.

 

Sodium hydroxide (Latin Natrii hydroxidum; other names — the caustic soda, a caustic soda, caustic rubbed, caustic alkali) — the most widespread alkali, a chemical formula NaOH. In a year in the world more than 57 million tons of a caustic natr are made and consumed.

 

Hydrate of an oxide of NaOH sodium - white solid substance. If to leave a piece of a caustic natr on air, then he soon grows stout as attracts moisture from air. Caustic rubbed well it is dissolved in water, at the same time a large amount of warmth is allocated. Solution of a caustic natr mylok to the touch.

 

Sodium hydroxide (caustic alkali) — the strong chemical basis (carry hydroxides which molecules completely dissociate in water to the strong bases), hydroxides of alkaline and alkaline and land metals of subgroups Ia and IIA of periodic system of D. I. Mendeleyev, KOH (caustic heat), carry to them Ba(OH)2 (caustic barite), LiOH, RbOH, CsOH. Alkalinity (basicity) is defined by the metal valency, radius of an external electron shell and electrochemical activity: the more the radius of an electron shell (increases with serial number), the easier metal gives electrons, and the its electrochemical activity is higher and the more to the left the element in an electrochemical number of activity of metals in which activity of hydrogen is taken for zero settles down.
Water NaOH solutions have strong alkaline reaction (pH of 1% solution = 13). The main methods of definition of alkalis in solutions are reactions to hydroxide ion (OH−), (with fenolftaleiny — crimson coloring and methyl orange (metiloranzhy) — yellow coloring). The more hydroxide ions is in solution, the alkali and the more intensively coloring of the indicator is stronger.
