What has the highest concentration of hydroxide ion?
The highest pH on the scale is 14. But pH over 14 is also possible: for example a sample of 1o M sodium hydroxide solution has a pH of 15.
What are intervals of pH?
Intervals of pH represent ranges of acidity or alkalinity. For example, pH 0-6 is acidic, pH 7 is neutral, and pH 8-14 is alkaline. These intervals help in categorizing substances based on their level of acidity or alkalinity.
Why does the pH scale ordinarily run from 0 to 14 is it possible for the scale to extent beyond 0 and 14if so how?
The pH scale is the negative of the logarithm of the hydrogen ion concentration (molarity) in a solution. Thus at pH 1 there are 1x 10-1 mol/liter of H+ present and at pH 14 there are 1x10-14 mole/liter present (much less) Obviously you could have 1x10-15 mol/liter present for a pH of 15 or even a fraction of of a mole to give a pH of less than 1 (pH 0.698 = 0,2 mole/liter.) At pH 0 the concentration would be 10 mol/liter Now what happens at lower than zero pH. Any acid that has a concentration of hydrogen ions with a molarity greater than 1 can be calculated to have a negative pH. The pH of 12M HCl would be -log(12) = -1.08. The proof of the concentration and pH would be physically difficult as the pH probes don't work well in this range (acid error).
What solutions is the weakest acid pH of 2.4 pH of 5.2 pH of 6.4 pH of 8.6 or pH of 10.1?
pH=6,4
What is the pH of tomatoes ketchup?
The pH of tomato ketchup is 3.85
What is pH soap?
15 pH
Why can a pH of 15 not be there?
In theory any pH is possible, especially at elevated temperatures where pure water decreases in pH because of increased ionisation (but it is still neutral, neither acidic nor alkaline). However, does anything dissolve at sufficiently high concentration, and ionise sufficiently at that concentration, to achieve any given pH? In practice there are limitations. At pH 15, hydrogen ion concentration is 10^-15. That makes hydroxide ion concentration 10^1 - 10M sodium hydroxide in theory would have a pH of 15.
What are true about the pH scale the scale ranges from 1 to 15 true or false?
False. The pH scale ranges from 0 to 14. A pH of 7 is neutral, with values below 7 being acidic and above 7 being alkaline.
Why the pH lies between 0 to 14 not 15?
This is only a convention.
The strongest base would have a pH of?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
What is the pH balance of dissolved aspirin?
there is no logical reason to believe that "acetylsalicyclic acid" would have a pH of 15...this would be a base.
What has the highest concentration of hydroxide ion?
The highest pH on the scale is 14. But pH over 14 is also possible: for example a sample of 1o M sodium hydroxide solution has a pH of 15.
What are intervals of pH?
Intervals of pH represent ranges of acidity or alkalinity. For example, pH 0-6 is acidic, pH 7 is neutral, and pH 8-14 is alkaline. These intervals help in categorizing substances based on their level of acidity or alkalinity.
What is the range for pH in chemistry?
Technically, the pH range is 0 to 14. 0 to 7 is acidic, 7 is neutral, and 7 to 14 is basic. However, in very rare situations, an acid can have a pH of -1 and a base can have a pH of 15. But I doubt you need to know that.
Strongest base a pH can have?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
