Hydrochloric Acid Solution, 2M, 500mL - The Curated Chemical Collection

I looked up a fairly common combination (at least for what I was using this for, copper-clad circuit board etching) of Hydrogen peroxide and this stuff, Hydrochloric acid, online that was just WICKED AWESOME! I believe it was 10% peroxide to 90% this stuff.. WOW! I warmed the mix up just a little in the microwave, slid my copper-clad board in, and was AMAZED! This stuff went to WORK! I had my CLEAN, paths all crisp and CLEAR, circuit board etched in UNDER 5 MINUTES! Awesome! I don’t know if it’s the president or EPA or what that makes buying chemicals like this so costly, but this stuff was WORTH IT!

Good for cleaning grout and correcting the PH on well water. PH here is 8-9, extremely hard water.

Works well

Got the job done for several experiments. Good quality.

Sometimes I feel like this is a little too diluted. But I use it to clean my marine. Sediment fossils.

i used this to test for lead in turmeric and was able to be reassured that the turmeric was safe

Pretty sure this has basically no acid in it. I've gotten it on my skin and let it set for hours without so much as it causing a itch. Would rate zero stars if possible.
