Is there another sbustance other than water with a PH of 7?

The normal rate of acid excretion through the kidneys gives urine a pH that falls between 6.75 and 7.25.\nWhen your body has the mineral reserves that it should, the abundance of minerals will show up in a saliva ph test as a pH reading of 7.0 to 7.50.\nCheck out acid base balance on the Net to find more.

Well, you're making a flawed assumption that something needs to be corrected. If the pH of the lake is 3 and there is life in the lake, don't you think it might affect the life if you neutralize it?\n\nIn response to the above answer, pee is an acid. If the lake has a pH of 3, it too is acidic. Peeing in it wouldn't do anything to neutralize it.

OH- is an alkali (pH is more than 7) and H+ is an acid (pH is less than 7).\n\nAcid + Alkali -> Neutrality\n\nSince it's neutral, water (pH 7) is produced.\n\nHope my explanation helped c",)

That would depend on what the system is, what the current pH is, what you are trying to accomplish (create a certain buffer, etc.)\n\nIf the current pH is > 7.5 you would use an acid (HCl, HNO3, etc.) to lower the pH.  If the current pH is < 7.5 you would use a base (NaOH, NH4OH) to raise the pH.

Br2 is extremely soluble in CCl4 - much more soluble than in water.\nLook up "partition".

one generally uses pure water as a base point. other liquids are typically refrenced as lighter or heavier than water.

we know that pH is ranged from totally basic to totally acidic, with neutrality (water) being at pH=7; so just display a range from 0 to 14 and color code it (red for acid and blue for basic) and place your findings there (ie before and after situations of NaCl towards the pH of the solution). Also place analogies (ie. the results of the pH due to NaCl concentration of 10% is equivalent to household ammonia)\n\nWhen explaining something to a non-science person, visuals and analogies always helps.

H2O2 can exist in many forms at pH = 7, \n\nH3O2+, H3O3- are among the possibilities.

pH (potential hydrogen) is a measure of the activity of hydrogen ions (H+) in a solution and, therefore, its acidity or alkalinity. In aqueous systems, the hydrogen ion activity is dictated by the dissociation constant of water (Kw = 1.011 × 10−14 at 25 °C) and interactions with other ions in solution. Due to this dissociation constant a neutral solution (hydrogen ion activity equals hydroxide ion activity) has a pH of approximately 7. Aqueous solutions with pH values lower than 7 are considered acidic, while pH values higher than 7 are considered alkaline..\n\npH = -log(concentration of H+)\njust use the equation to figure it out.\nhttp://en.wikipedia.org/wiki/PH

No surprise at all, the transition does not take place at an pH of exactly 7 but already before. Take a look here for a graph:\n\nhttp://antoine.frostburg.edu/chem/senese/101/acidbase/faq/indicating-strong-or-weak.shtml

how were you measuring the pH? if it was a pH meter maybe it wasn't calibrated correctly/ recently?? or if it was with litmus paper.... maybe it went bad? I'm not sure if it can... check and see if there could have been an expiration date. i don't think temperature would have that drastic of an effect unless you did the experiment at pH7 and a seriously high (like about 60C) temp and the other ones at room temp or 37C (body temp)... sorry i cant help anymore then that, that's very strange!

Concentrated Sulfuric Acid, Concentrated Hydrochloric acid, Concentratic Nitric acid...almost all concentrated acids will read out at pH 1

YES, EG. SALIVA FOR EXAMPLE IS MORE BASIC THAN ACIDIC, AS IS ALSO  HUMAN BLOOD. THE Ph OF BLOOD IS 7.62,  NEUTRAL Ph IS 7.0.

How about the red fountain experiment with acids and litmus solutions? mail me at pr4kane@yahoo.com for furhter details on it. u can try electroplating,bleaching by chlorine/so2,the brown ring test with sulphuric acid etc.

Any acid, for example:\n\nHCl + H2O  --> Cl- + H3O+

mostly acids. do your own homework

The question makes no sense.  A single, isolated anion has no pH value.  pH refers to the H+ concentration in aqueous solutions.
