Reaction of Pepto Bismol and HCl: What are the Products?

[dbny116]

What are the products when Pepto-Bismol and HCl react together.
I know a salt and water.
But what exactly?

I believe pepto bismol is C7H5BiO4

So C7H5BiO4 + HCl --> ?

well, yes, Bismuth subsalicylate is C7H5BiO4, but the problem is, there are ALOT of other ingredients in Pepto bismol (specifically: benzoic acid, flavor, magnesium aluminum silicate, methylcellulose, red 22, red 28, saccharin sodium, salicylic acid, sodium salicylate, sorbic acid, water.) so you are going to have a lot of impurities in your products. (plus, a few of the 'inactive ingredients' will likely react with HCl also)

The reaction between Pepto-Bismol (C7H5BiO4) and HCl (hydrochloric acid) results in the formation of a salt and water. The salt formed is bismuth subsalicylate (BiC7H5O4) and the water is a byproduct of the reaction. This reaction is commonly used to treat stomach upset and discomfort. The bismuth subsalicylate acts as an antacid and helps to neutralize excess stomach acid, while the water helps to soothe the stomach lining.
