Sodium Hypochlorite Solution USP Grade
NaClO --- 74.44 --- [CAS 7681-52-9].
Hypochlorous acid, sodium salt.

Sodium Hypochlorite Solution contains not less than 4.0 percent and not more than 6.0 percent, by weight, of NaClO.
Caution: This Solution is not suitable for application to wounds.

Packaging and storage: Preserve in tight, light-resistant containers, at a temperature not exceeding 25C.

Identification:
A: The Solution at first colors red litmus blue and then bleaches it.
B: The addition of 3 N hydrochloric acid to the Solution causes an evolution of chlorine.
C: The solution obtained in Identification test B responds to the flame test for Sodium.
Assay: Weigh accurately, in a glass-stoppered flask, about 3 mL of Solution, and dilute it with 50 mL of water. Add 2 g of potassium iodide and 10 mL of 6 N acetic acid, and titrate the liberated iodine with 0.1 N sodium thiosulfate, adding 3 mL of starch as the endpoint is approached. Perform a blank determination, and make any necessary correction. Each mL of 0.1 N sodium thiosulfate is equivalent to 3.722 mg of NaClO.
