Large number of people have the habit to drink water in the morning,
right after they wake up. Probably your parents have told you that it is
If you have this strange habit, probably you have noticed that the
water have strange taste.The food contains sugars and proteins which
cans be easily targeted by microbes and to come to pollution. Although
regular water does not contain any of these nutrients and there is no
explanation from which comes the strange taste in the water that stood
on the nightstand over the night by your bed.
Still, there is large amount of dust and bacteria that can be
gathered in that glass of water. When water is exposed to air it absorbs
carbon dioxide and a small part of that CO2 is converted into carbonic
acid, which means that water exposed to the air changes its chemical
composition. So, when carbon acid releases one or two protons and is
turned into carbonate or bicarbonate, it lowers the pH of water and
changes its taste.
The water actually is not bad, but certainly has changed the taste
after standing all night in the nightstand and gathering bacteria and
dust from the air.
After reading this, surely you will think twice if you should or should not drink it.
