what is the recommended standard of reusability (how many trips?)of a 19Liter refillable PET Bottle.?

every per bottle has a marking at its bottom...a triangle with the numbers 1 2 or 3....the ones marked with 1 should not be used more than once due to the change in chemical compositions taking place in it.how ever the ones marked with higher numbers can be reused...but not 4 very loong.

Make sure its a big bottle with a wide opening so you can easily slide in to do your business and not cause any leakage. Try a large lemonade bottle, that way you can easily carry it with you in case you wanna empty it. And no one will stare because they will think its lemonade. I would recommend Gatorade, just don't pee while driving or you might hit someone. Good luck with your trip.\nAnd yes, I have used bottles before, its a hasstle sometimes to go to a public restroom especially at the gas stations, plus they stink cause people pee on the floor or donot flush. I think its much cleaner going in a bottle.

Hey, so far you got no useful answers. You clearly stated you were travelling within Canada from Winnipeg to Toronto and yet you got a slew of American answers. . I really don't know why your bottle was confiscated.  In the past I have travelled with sealed bottles in my carry-on luggage.Was it recently when no liquids were allowed in carry ons?. If I were you I would call Canada Customs, give the flight dates and ask what the rule is in general.

For the plastic bottles: \n98-99% PET or PETE, polyethylene teraphthalate. The remainder consists of additives, mostly antioxidants and anti-clouding agents, used during PETE production.\n\nFor the glass bottles:\n0% in the glass, but 85-90% of the paint is petro-based.  And most glass manufacturers get 100% of the energy used to melt and form the glass from petroleum.

42 us gallons.\nthis is the standard used by the petoleum industry, think about it you cant put 55 gallons of oil in a 55 gallon container once it heats up and expands you have problems eh.

Currently, the polymer sodium polyacrylate.  It is nicknamed "super slurper" because it can absorb 400-800 times its body weight in water.  Oh yeah, it is used in a variety of applications, including diapers.  Pretty cool, huh?

Apparently, the EPA proposed a limit of 300pci/L 10 years ago (numerous web-based sources including the EPA). The site at this link talks more about the problem and has a lot of information as well as actual data of levels in many supplies.\nhttp://www.ewg.org/tapwater/contaminants/contaminant.php?contamcode=4004

In my county in Maryland, we have recycling of glass, plastic, and mixed paper with weekly pickup at our houses. There seems to be widespread participation and it's much more convenient than lugging your bottles back to the store.

It means that it is recyclable. The number indicates the type of plastic. The numbers are\n1 = Polyethylene terephthalate\n2 = High-density polyethylene\n3 = Polyvinyl chloride\n4 = Low density polyethylene\n5 = Polypropylene\n6 = Polystyrene\n7 = Any other plastics

I think you may be talking about a volumetric flask, shown on this page:\n\nhttp://www.hometrainingtools.com/catalog/chemistry/glassware-plasticware/cat_beakers-flasks.html?products_begin=20

Want to see something neat??\n\nType "19 gallons in cubic feet." into google.\n\nWorks for all kinds of conversions.

Take, say, a standard 2M solution and dilute it by a factor of 20.\n\nThat is, add 19cm3 of water to 1cm3 of 2M HCl.

The CRC Handbook of Chemistry and Physics has all kinds of good information like that (although it is pricey).\n\nOr, search the web for the specific liquid of interest.
