Specifications of Lithium Hydroxide USP Grade:
LiOH-H2O --- 41.96
LiOH --- 23.95
Lithium hydroxide monohydrate CAS 1310-66-3.
Lithium hydroxide Anhydrous CAS 1310-65-2.

Lithium Hydroxide contains NLT 98.0% and NMT 102.0% of lithium hydroxide (LiOH), calculated on the anhydrous basis.

When moistened with hydrochloric acid, it imparts an intense crimson color to a nonluminous flame.
Chloride and Sulfate, Sulfate:
Sample: 2.0 g
Acceptance criteria: It shows no more sulfate than corresponds to 1.0 mL of 0.020 N sulfuric acid (0.05%).
Sample solution: Dissolve 3.33 g in 50 mL of 3 N hydrochloric acid. Boil the clear solution to expel carbon dioxide, add 5 mL of ammonium oxalate, render alkaline with 6 N ammonium hydroxide, and allow to stand for 4 h. Pass through a filtering crucible, and wash with warm water until the last washing yields no turbidity with calcium chloride. Place the crucible in a beaker, cover it with water, add 3 mL of sulfuric acid, and heat to 70C.
Analysis: Titrate the Sample solution with 0.10 N potassium permanganate to a pale pink color that persists for 30 s.
Acceptance criteria: NMT 3.34 mL of 0.10 N potassium permanganate is consumed (0.20%).
[Note: While pipeting and during the subsequent titrations, keep the contents of the flasks blanketed with a stream of carbon dioxide-free air.]
Analysis: To the flask containing the completed Final titration obtained in the ;Assay, add 1 drop of methyl orange TS. Titrate with 0.1 N hydrochloric acid VS until a persistent orange color is produced and no undissolved barium carbonate remains. Perform a blank titration to determine the volume of 0.1 N hydrochloric acid consumed in going from the PhPh endpoint to the methyl orange endpoint. To 100 mL of carbon dioxide-free water in a 250-mL conical flask, add 3 drops of the Sample solution from the Assay, 20 mL of 1 N barium chloride, and 3 drops of PhPh TS. Allow to stand for 2 min. Titrate this solution with 0.1 N hydrochloric acid. At the discharge of the pink color of the indicator, add 1 drop of methyl orange TS, and titrate with 0.1 N hydrochloric acid VS until a persistent orange color is produced.
Acceptance criteria: The titration shows no more carbon dioxide than corresponds to 1.5 mL of 0.10 N hydrochloric acid (0.7%).
Lithium Content: To pass the test by Flame photometry.
Acceptance criteria: 28.1% to 29.9% on the anhydrous basis.
Water Determination:
Analysis: Dry at 135C at a pressure of NMT 5 mm of mercury for 1 h.
Acceptance criteria: 41.0% to 43.5%
