Hydrochloric Acid 37% Solution, ACS Reagent Grade-1 Quart

Using this with barium chloride to test my stash of potassium nitrate and potassium sulfate. Container labels are gone with the wind.Bottle itself is impressively packed. Sealed plastic bag inside another sealed plastic bag, inside a box stuffed with those big rice puffs. I like effective leak protection for a chemical product.

Exactly what I needed for a project that I hope will change the world for the better.

It is what it is, pretty much a lifetime supply of hci for my use, which is copper plating, because I only use ONE DROP per batch. I've used it and it works, so the listing is accurate and the seller is doing a good job.

There was a small issue with shipment, Stellar Chem. Corp. was extremely helpful and quick to resolve the complication. Highly recommend, products are as described.

the plastic bottle mouth/opening is seal with a plastic lined foil, the seal should be carefully removed completely, as Aluminum foil will react with HCl. There is a some kind of soft material disk inside the cap, I guess it is used as a seal, it also react with 37% HCl, it should also be removed.

Strong/powerful HCL. Fuming HCL; so use in a well ventilated area, with a full face respirator or with an exhaust hood.

Which I would have read the reviews closely. As others have said, once the foil seal was removed the liner on the under surface of the cap completely degraded and blackened which then dropped into the solution and contaminated the entire bottle. Needs to be shipped with an acid proof cap.

It does the job, the kitchen grout is back in its original light grey.
