AI Thread Summary
When Pepto-Bismol, primarily composed of bismuth subsalicylate (C7H5BiO4), reacts with hydrochloric acid (HCl), the expected products are primarily a salt and water. However, the complexity arises from Pepto-Bismol's formulation, which includes numerous other ingredients such as benzoic acid, flavoring agents, magnesium aluminum silicate, methylcellulose, various colorants, saccharin sodium, salicylic acid, sodium salicylate, and sorbic acid. These additional components can lead to a variety of reactions with HCl, resulting in multiple byproducts and impurities, complicating the overall reaction outcome.

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 --> ?
 
Chemistry news on Phys.org
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)
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
