Water can be reactive with many compounds in organic chemistry.  More specifically, it will protonate or deprotonate your reaction intermediates and possible give undesired products.

you can't mix oil and water they will always be seperated.  Oil and water have different polarities so that if you try to mix them in a short period the oil will come on top of the water.

Dissolved materials that can precipitate out of solution can cause problems with appliances. They are a particular problem with systems that heat water, because this increases precipitation and causes scale. This can reduce efficiency of heating elements, and can block pipes.\n\nHeating systems suffer less, because it is always the same water, so once the solids have deposited out there are no more to add to the scale, and this is very little scale. However, other dissolved materials can cause problems by leading to corrosion.

Okay...\n\nFor starters, water is H2O. We can make H2O by burning hydrogen gas in the presence of oxygen, easy, but then where would we get enough hydrogen gas to make even a noticeable amount of water? Besides, the problem isnt finding H2O--it's producing clean water. Most of our planet is under water, and there's tons of water vapor in the air. The difficulty is getting a large source of water where peole live, purifying it, and keeping it clean until it gets to people's homes.\n\nThe shortages in your area may be because there's just no ready source of water there, or because your community uses way too much of it. Environmental stuff like seasons play a part, too. There's usually less water in reservoirs during summer because of the decreased rainfall and increased evaporation.\n\nSometimes science isn't the problem. We already have more than enough technological remedies for every little inconvenience. Start conserving water, and you won't have to worry about shortages.

I agree.  They pretty much all need water, but they can take up many different substances.  In some circles, it is believed that for every substance in the world, there is a microorganism that can break it down.  Things like nitrogen, different carbon sources and a polethora of other things are commonly taken up by bacteria.

A few years back there has been a rumor around the internet regarding drinking from a reused plastic water bottle.  The rumor has it that carcinogens in reused plastic water bottles leach into the drink making it poisonous.  This is another urban legend spread through the internet and it's completely unfounded.

depends on the strength of the base actually.  water is amphoteric which means it can act like an acid or a base.  if a weak base is put in water the water can neutralize it, but water is quickly overrun yielding the below equation.\n\nB + H2O yields HO- +BH\n\nthis makes the water basic.

I've read bad things about bacteria that form in used water bottles that sit for awhile without being thoroughly washed AND dried first. I'd throw it away and start with a new bottle of water.

because water is a renewable resource. There is as much water on the earth today as there was when the earth formed.  The argument that not all of that water is as drinkable today as it was then is a weak one. The water from a treatment plant (post treatment) is usually cleaner than plain tapwater!

nobody shud waste water . that is presserve water .  water harvesting which is done wen the rains come can be done as its a good method ..

I assume this is based on the principle of Osmosis. I would like a bit more data before answering further.

B.  As the matter settles in the bottom of the basin.\n\n"There are a wide range of techniques that can be used to remove the fine solids, micro-organisms and some dissolved inorganic and organic materials. The choice of method will depend on the quality of the water being treated, the cost of the treatment process and the quality standards expected of the processed water" - wikipedia

You need to get a device called a 'water rehydrator'. It essentially rehydrates powdered water. They are pretty expensive though...
