All bar soaps have sodium hydroxide in them. How many kids have had bar soaps in their mouths for swearing lmao.
Even if you ate that bar of soap you'd be fine.
Like i said, they already add 100ppm to city drinking water as a disinfectant everyday. None of it reaches your faucet. Most of the amount he added would have added would likely have been absorbed along the way.
But like you said concentration matters. I wonder what the exact concentration would have been at the faucet if it wasnt caught.
Sodium hydroxide may be used in the making of soap (I don't know I'd have to look it up but I don't care, I know chemistry), but it is not "in soap." That's not how chemistry works.
Maybe, but soap is not a NaOH solution.
Again, I'm not going to look it up because its irrelevant. If you add it to water as a disinfectant you are doing one of two things, neutralizing overly acidic water, or killing bacteria (because it strongly kills things). If you use it to kill bacteria you can then follow up with an acid to neutralize it.
Again, do NOT consume NaOH. EVER.
Yeah no doubt, it can be absolutely dangerous. But hydrochloric acid will absolutely destroy you, but can be completely neutralized with a 1:1 ratio of water.
After leaving the treatment plant it would be introduced to a million gallons of water.
What concentration would that have been when it reached the faucet? Hard to tell, im sure someone can figure it out. They increased the concentration 100x at the facility. But there are several more steps to the treatment before even leaving the facility.
Im not downplaying the possibility of how dangerous it is, but the concentration at the faucet would likely have been nothing more than a mild irritant.
For example, apples contain arsenic and cyanide. Concentration matters.
No! Please look up Saponification. There is a chemical reaction between fats and lye (sodium hydroxide), and what remains is a type of salt. This is why real soap tastes salty. If you have lye heavy soap, it can burn your skin. Soaps/detergents might say lye/sodium hydroxide, but that's what goes into making them, not what's left in the final product.
If you've seen Breaking Bad, Sodium Hydroxide is what they put in the bathtub. They also used it in Fight Club when making soap with fat.

Agreed. The fact they can mess with drinking water is terrifying, though.
I worked at a plant way back when and we talked about that all the time. Our infrastructure is basically unprotected. Definitely terrifying that it was done online.
No, no, no, no, no...
HCl can be EXACTLY neutralized by a 1:1 with NaOH. This produces a salt [NaCl] water precipitate with neutral pH.
HCl and NaOH are sorta opposite sides of the same toxic coin. They are both pretty much equally harmful at equal concentrations.
A 1:1 solution of HCl and H2O produces an extremely high molar concentration of Hydrochloric Acid. PLEASE PLEASE PLEASE DO NOT MAKE SUCH A SOLUTION AND CONSUME IT. IT IS NOT NEUTRAL!!!!
You would literally melt. Same as a 1:1 solution of NaOH and H2O.
Please learn chemistry before giving advice on chemical consumption safety. Please. I'm not trying to be demeaning. Please.
There is no NaOH at the faucet. That's not how it works. NaOH in solution splits into the ions Na+ OH-. In a bottle these will for the most part stay in the solution and do nothing. But in a system where it moves, flows, encounters other things such as a cities water supply, the OH- will be neutralized by other things (free H+ from random acids) and the Na+ will either stay in solution or precipitate out with other ions it may encouter (such as Cl-).
It also may be that a cities water supply is slightly basic and there is a predominance of OH-. I don't know, also don't care. That is not a proof that NaOH is "safe" in any way shape or form for consumption.
In this we are in complete agreement.
Sorry its 1:1 with NaOH, but 1:10 to neutralize HCL in water which gives you what a ph of 7? But thats a typo that i will correct.
If NaOH completely disassociates in water then it would never make it out of the plant, which is my point. You have the disinfection stage, then filtration, sedimentation and settling, a chemical coagulation and further settling, aeration, etc etc.
Thats all before it joins the rest of the city water and pumped into a tower, before returning down to city pipes then to your house. It would come in contact with millions of gallons of water and loads of heavy metals along the way from zinc coated steel pipes and lead.
I have a little bit of a chemistry background and worked a water treatment plat for few years in my youth so no need for the condescending tone.
To me this seemed more like an attack on the plant itself then an attempt to poison the water supply. It probably made one hell of a show at the plant when they introduced all that NaOH to water.
