Commercial aspirin is pretty much odorless.
If you detect a "vinegar" smell, the active ingredient - acetylsalicylic acid - is breaking down. To avoid this, store aspirin where it's cool, dark and dry, in a airtight container, buy the freshest aspirin you can find (usually the best selling brand/size in the store) and don't expect it to live forever.
I used to keep aspirin in the glove box, so it'd be handy, but closed cars in the summer sun get hot, so I learned to replace it every Halloween so I'd have good aspirin when I needed it.
Yes because there is a filler in commercial aspirin
I believe that Bayer was the first commercial producer of aspirin.

No. Before she was famous, she was in an odor-eaters commercial.

The smell of vinegar from an old bottle of aspirin is an indication that the active ingredient in aspirin, acetylsalicylic acid, has decomposed. One of the products of the decomposition of aspirin is acetic acid, which is the active ingredient in vinegar and what smells. You should definitely not consume drugs that are past the expiration date that have decomposed! You may need to discard it because some meds can be toxic after a certain date, or after being exposed to sunlight, humidity, etc. As cheap as aspirin is these days, one should not hesitate to replace it if there are any questions at all about its freshness.
The salicylic acid in the aspirin will help keep the water clean and free of flower damaging bacteria. The flowers will keep longer
There is no difference unless the commercial application is used as a propellant then it will not have the ethyl mercaptan added which gives it the strong odor.
