Frequently Asked Questions
What is Sodium Bicarbonate USP Grade 5?
Sodium Bicarbonate USP Grade 5 is a coarse granular sodium bicarbonate manufactured by Church & Dwight under the Arm & Hammer brand. The manufacturer's USP specification requires an assay of 99.0% to 100.5% NaHCO3 on a dried basis.
Is sodium bicarbonate the same as baking soda?
Yes. Baking soda is a common name for sodium bicarbonate. Other names listed by Church & Dwight include bicarbonate of soda and sodium hydrogen carbonate.
What does USP mean in Sodium Bicarbonate USP?
USP refers to the United States Pharmacopeia. Church & Dwight's specification for this product includes USP identity, assay, purity, and related quality requirements.
What is the purity of Sodium Bicarbonate USP Grade 5?
The USP specification lists an assay of not less than 99.0% and not more than 100.5% NaHCO3 on a dried basis.
What does Grade 5 mean for sodium bicarbonate?
Grade 5 is Church & Dwight's product grade designation. The supplied specification identifies Grade 5 as a coarse granular sodium bicarbonate and provides defined particle-size limits using U.S. sieve sizes.
Is this a 50 lb bag of baking soda?
