No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Certain types of beverages can definitely cause some types of cans to erode, yes. You'd have to know whether or not your aluminum bottle has an interior lining or not. There are also different types of linings.
Unfortunately, I only know these things from a friend who works in the canning industry so I can't speak to them with any degree of detail. But some manufacturers get their beverages tested and then have to can them in certain types of cans for that reason.
I have a Quechua bottle that looks slightly yellowish/golden on the inside. Might that be some sort of lining?
that's probably just anodized aluminum (not lining)
~~The yellowish color isn't lining, lining is only in aluminum cans because it's cheaper and easier than using thicker aluminum and is usually clear (unless stained). The lining is what gives the cans structure, usually made of epoxy and/or bpa plastic. Without the lining, you can tear a soda can like double thick tin foil. No need for lining in a steel bottle.~~ see the comment below by @schmidtster for the actual use of lining in metal containers, that's what I get for trying to use something I was told in highschool chemistry.
~~The yellow/golden color on the inside of your bottle is just the metal being stained. Stainless steel isn't really stainless, just harder to stain because the chromium in it forms its own layer of oxidation that protects from being directly touched. Best guess is that the lemon you put in your water breaks down that oxidation layer before you can drink enough, then the lemon and vitamins/minerals/coloring in the tablets stain the metal~~ I misread op, they have an aluminum bottle so the stainless steel part doesn't matter. As far as I can tell from the website, the aluminum bottles don't have a lining (no bpa, didn't say no epoxy). From the inside being yellow I still think it's stained by the lemon and tablets even if it's lined, especially if it didn't start that way
in some cosmic sense yeah there will be equilibrium after some time but most of the time it's just called "corrosion"
I believe the distinction is necessary, corrosion would be the entire bottle “dissolving” which wouldn’t happen with water. With leaching only a few elements would transfer.
What? Corrosion is the surface oxidizing, not the entire thing dissolving.
When the surface oxides, that layer get removed, than the surface oxides, that layer disappears. Repeat ad-nauseam until it’s completely gone.
Dissolving is oversimplifying, but eventually the entire thing will disappear with corrosion.
