What are the advantages of transporting milk in glass bottles as opposed to plastic cartons?
While less used today, transporting milk in glass bottles generally provides better protection for the milk. Glass bottled milk also tends to taste better, and are more environment friendly than plastic.
What are the reasons for the use of glass-stoppered bottles for acids and plastic-stoppered bottles for bases?
It is mostly avoidance of glass-glass seals for bases, particularly strong alkalis, that is required. Glass is slowly attacked by strong alkalis and many bases react with atmospehric carbon dioxide - both reactions can lead to the formation of compounds that effectively cement together a glass-glass seal. You get the same reactions within a rubber/plastic-glass seal, but the plasticity of the seal makes the stopper relatively easy to remove.
Is SODIS just as effective with glass bottles as it is with clear plastic PET bottles?
Generally speaking, glass bottles will work for the SODIS process although they are much thicker walls and generally do not allow as much UV radiation through as thin walled clear plastic PET bottles which are the container of choice. The main disadvantages of glass bottles are the weight and the fact that they can break if dropped. They are also not as plentiful in the rural areas of developing countries where this process is being targeted at the household level. Another disadvantage is the lack of screw top lids found on plastic bottles. They are more difficult to cap and prevent leakage during the process.
What is bottle made of?

Is bottled water from plastic bottles worse than those in bottled in glass?
Water in plastic bottles is not necessarily bad, however, recent studies suggest that reusing them over and over can be harmful as they begin to degrade into the water you are drinking. Whenever you buy bottled water be sure to check where it's from. A general rule of thumb is that the water should be bottled north of your location as it will be cleaner than water bottled south of you (as most rivers generally travel north to south). There is a concern about consuming any product -- food or drink -- that has been stored for any length of time in a plastic container that has BPA or Bisphenol A. There are two camps: one that claims BPA is deadly and the other that says such claims are nonsense. To this end, many bottled products, plastic food storage containers, baby bottles and pacifiers, etc. are not being labeled as containing NO BPAs. Glass does not contain BPA, hence the big push for consumer to invest in glass water bottles coated in silicone. Read for yourself: http://www.factsaboutbpa.org

What are the reasons for the using glass-stopper bottles for acids and plastic stoppered bottles for bases?
If strong bases are present in the glass-stopper bottles, they may react with the glass and etch it or change the concentration of the base. Hence plastic-stopper bottles are used for bases.
Why do sportsmen use plastic bottles?
They're lighter and more rugged than glass bottles.
Why should we use plastic-stoppered bottles for bases?
