HOW TO PREPARE 3N OR 3M AMMONIUM HYDROXIDE AND 0.2M, 0.4N BARIUM HYDROXIDE

Ammonium hydroxide

Ammonia solution, also known as ammonium hydroxide, ammonia water, ammonical liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or simply ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH₃. Wikipedia


Molar mass: 35.04 g/mol
Formula: NH₄OH
Density: 880 kg/m³
Boiling point: 24.7 °C
Melting point: -91.5 °C

Ammonium hydroxide, 3 M, 3 N. Dilute 200 ml of concentrated solution (14.8 M, 28% NH3) to 1 liter.

Barium hydroxide
Chemical Compound

Barium hydroxide are chemical compounds with the chemical formula Ba(OH)₂ₓ. The monohydrate is known as baryta, or baryta-water, it is one of the principal compounds of barium. This white granular monohydrate is the usual commercial form. Wikipedia
Formula: Ba(OH)₂
Molar mass: 171.34 g/mol
Melting point: 78 °C
Boiling point: 780 °C
Density: 3.74 g/cm³
Soluble in: Water

Barium hydroxide, 0.2 M, 0.4 N. Saturated solution, 63 g per liter of Ba(OH)2.8H2O. Use some excess, filter off BaCO3 and protect from CO2 of the air with soda lime or ascarite in a guard tube.
