Appearance of solution
The solution is clear and colourless.
Dissolve 1.0 g in 10 ml of water.
Carbonates
Maximum 2.0 per cent, calculated as Na2CO3 as determined in the assay.
Chlorides
Maximum 50 ppm.
Sulphate
Maximum 50 ppm.
Iron
Maximum 10 ppm, determined on solution S.
Heavy metals
Maximum 20 ppm.

Sodium Hydroxide USP NF Grade Specifications

Sodium Hydroxide
NaOH 40.00
Caustic Soda Pellets
Sodium hydroxide CAS 1310-73-2

Sodium Hydroxide contains not less than 95.0 percent and not more than 100.5 percent of total alkali, calculated as NaOH, including not more than 3.0 percent of Na2CO3.
Caution—Exercise great care in handling Sodium Hydroxide, as it rapidly destroys tissues.

Identification— A solution (1 in 25) responds to the tests for Sodium.
Insoluble substances and organic matter— A solution (1 in 20) is complete, clear, and colorless to slightly colored.
Potassium— Acidify 5 mL of a solution (1 in 20) with 6 N acetic acid, then add 5 drops of sodium cobalt nitrite TS: no precipitate is formed.
Heavy metals— the limit is 0.003%.

REQUIREMENTS
Identification: A 1:25 aqueous solution gives positive tests for Sodium.
Assay: Not less than 95.0% and not more than 100.5% of total alkali, calculated as NaOH.
Arsenic: Not more than 3 mg/kg.
Carbonate: (as Na2CO3) Not more than 3.0%.
Insoluble Substances and Organic Matter: Passes test.
Lead: Not more than 2 mg/kg.
Mercury: Not more than 0.1 mg/kg.
