Pure water is assumed to be pH 7, right in the middle. It is neither an acid nor a base.
zero
The water is nutral so it is at Ph 7
Water found in nature is never pure. Because of it's polarity, water naturally attracts most minerals. In order to get pure water, it must be filtered many times to remove all the impurities.
distillation
The answer depends primarily on the scale that you are using. On the Celsius (or Centigrade) scale, under normal atmospheric pressure, pure water boils at 100 deg.
7
On the pH scale, it is in the middle. Therefore, pure water is neutral.
zero
The water is nutral so it is at Ph 7
Pure water has a pH of 7.0 which is the center of the pH scale.
It is the temperature scale on which pure water freezes at 32° and boils in standard pressure at 212°.
Yes.
its celsius
Water is considered a pure substance because its pH is 7, which is right in the middle of the scale from 0-14.
pure water is neutral with a pH of 7
+32 for "pure" water. Zero for very salty water.
Pure water at STP boils at 100 degrees Celsius, which is 373.15 Kelvin.
