Yeah, there is risk of some chemistry happening at really low voltages which cause irreversible changes to the structure of the material. Given how the battery responded to tests afterwards, I can only presume that these didn't happen. Short of dissecting the cells and putting them through XRD. Mind you, I do know a few people in the lab...

First question first. The ions in the salt dissociate with one another and more or less freely flow in the water.

Second, as far as I know, the hypochlorite ion has a covalent bond holding it together. It's just not a very stable bond.

Hey, maybe it is true and they've been using this location as their central reserve equivalent. Announcing this is clearly intended for the locals, to encourage them to storm the place so Israel doesn't have to, regardless of whether it is true. Combined with their announcement that they won't target it, it seems like they're encouraging people to go there. But instead it was evacuated. If it is a safe spot with no gold, why would they evacuate it? Anyway, the mind games are interesting...

Soap does it differently, allowing non polar molecules (like oils) to be dissolved in water by acting as a bridge between the two. It usually doesn't actually modify the compounds. Just acts as an adapter.

Bleach has more in common with acid based cleaners in the chemical disruption sense.

Just don't mix bleach and acids or you might actually die.

If there are only two competitors for a product, then it is either a niche product or there is room for more competition, usually, who can use disruptive marketing.

The problem is, for very large markets, companies will abuse their position to prevent competition from forming. Coke and Pepsi should not be allowed to simply buy every new drink that comes to market.

Anyway, I digress. The government doesn't have the balls to bust monopolies anymore.

So anyway, where was I...?

I guess teaching them to like baths early is your next task haha.

Gacha mechanics are patentable in games in Japan?

Man, patents just need to go away.

Tl;dr: Bleach is a salt with one of the ions being unstable. When that ion decomposes, the resulting oxygen and chlorine are disruptive to other chemistry.

Salts refer to the type of bond involved -- ionic bonds. Typically a salt is a positive ion and a negative ion that just sort of stick together due to their charges. These bonds aren't very close, and a salt molecule is easily dissolved in water. Once in water, the ions just sort of mix freely with the water molecules.

So here's the thing. Household bleach is sodium hypochlorite, which is technically a salt. They just sell it already dissolved in water at the right strength. The sodium ions in it is identical to the sodium ions in table salt. But the hypochlorite is the key here. This ion is made of a single oxygen and a single chlorine bound to one another. The hypochlorite isn't actually that stable (the solid form could be used as an explosive, actually), and in the presence of other molecules, tends to break down releasing oxygen and chlorine, neither of which are stable by themselves and will prefer to bond to something immediately. Both oxygen and chlorine are strongly electronegative and will bind fast and hard to other organic materials in such a way that they disrupt those materials. After the materials are disrupted, they tend to dissolve easier in water for removal.

Tangent: most household bleach has a significant amount of sodium chloride in it, as a byproduct of the manufacturing process. And it isn't worth it to purify the sodium chloride out of it so they just leave it in there.
