Does fresh water have a 7 pH?

Question

is fresh water ment to have a ph level of 7 and if it does what is that telling me about the water

Answer 1

A pH of 7 is considered neutral, or having an equal number of H+ and OH- ions. (H+, or hydrogen ions cause acidicity; OH-, or hydroxide ions cause basity; when combined H+ and OH- create H20, which is water).

Fresh water theoretically may have a pH of 7, but pH varies throughout any conditions, including temperature and location.

Answer 2

Yes. The pH scale is from 0-14. Under 7 is acidic. Over 7 is basic. 7, being right in the middle, is neutral, which is where water is supposed to be.

Sometimes, people squeeze fresh lemon in their water for the taste. This makes it very slightly acidic so the body absorbs it better.

Answer 3

Disteilled water, not "fresh". Fresh water from the most pure spring will have dissolved minerals which will affect PH. Even dissolved carbon dioxide will make distilled water acidic. I operated a machine that detected ions dissolved in a solution of distilled water and alcohol to determine if there were residues frrom manufacturing processes on a product. The machine could actually detect the change if I blew bubbles int the solution.

Answer 4

Most fresh water ponds and lakes have a ph between 6 and 8

Answer 5

pure water will have a pH of seven. most lakes and ponds have a pH from 6 to 8.

a high or low pH can be caused by fertilizer runoff or if the balance of organisms is off. a basic or acidic pH can be very bad for many plants and animals, so the problem should be corrected as soon as possible.

Answer 6

Dont add ph chemical! it just makes the ph bounce and that can kill fish. What is the ph of your tap water? or the water you add to the tank? It is likely that the ph will settle to that ph after the tank is finished cycling. you need to get liquid test kits for ammonia, nitrite and nitrate, and Ph a cycled tank has zero ammoni, zero nitrite and some nitrate, nitrate is best kept at 20. the nitrogen cycle in short = ammonia- aka "decaying waste" enters tank- an army of bacteria come and turn ammonia into nitrites. then a new army of bacteria come in to turn nitrite into nitrate. then it is safe to add a small amount of fish. and more bacteria develope to accomade the larger amount of waste., so adding more then 2-3 fish every 3-5 days could bee to much for the current "army of bacteria" to handle, and then you have a mini cycle. not good! Ammonia and propobly nitrites affect Ph, so an uncycled tank often has a bouncing Ph, bad for fish!

Answer 7

yes only the fresh water has it, but not the flavor kind.
