PHYSICAL AND CHEMICAL PROPERTIES OF NAOH – SODIUM HYDROXIDE

 

Physical Properties

NaOH – Sodium hydroxide is a viscous solution that can damage fabric, paper, and corrode skin. Use with extreme caution.

In solution it forms the monohydrate NaOH.H2O at 12,3–61,8 °C with a melting point of 65,1 °C and a density in solution of 1,829 g/cm3.

Chemical properties

NaOH – Sodium hydroxide is a strong base: turns litmus blue, phenolphthalein solution pink.

Reacts with acids to form salt and water: NaOH(aq) + HCl(aq) → NaCl(aq) + H2O

Reaction with acidic oxides: SO2, CO2…

2NaOH + SO2 → Na2SO3 + H2O

NaOH + SO2 → NaHSO3

Reacts with organic acids to form its salts and hydrolyzes esters and peptides:

Ester hydrolysis reaction

React with salt to form new base and new salt (condition: after reaction, precipitate or vapor must be formed):

2NaOH + CuCl2 → 2NaCl + Cu(OH)2↓

Reaction of some amphoteric metals (Al, Zn...): 2NaOH + 2Al + 2H2O → 2NaAlO2 + 3H2↑ 2NaOH + Zn → Na2ZnO2 + H2↑

Reaction with amphoteric compounds: NaOH + Al(OH)3 → NaAlO2 + 2H2O 2NaOH +
