Kw of water changes when temperature changes. Usually the temperatue is 298K , Kw is a constant:10exp-14, so when you test pH, the (H+) is less than 10exp-14.
I don't think there is one. The pH scale only goes up to 7.
The PH scale is the measurement of acids and bases. 8 and up are bases. 6 and lower are acids. 7 is neutral.
A pH scale up to 7 indicates acidity, with lower values being more acidic. pH 7 is neutral. A pH scale up to 8 would still be slightly acidic, with substances becoming more neutral as the value approaches 7.
the pH scale
the pH
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
The Ph scale doesn't have units it's a model to show where solutions rank based on the -Log of the concentration of H+ ions
strawberries are at 3.5 on the pH scale
The Ph scale does not have colours.
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
A pH of 0 is the most acidic on the pH scale.
The pH of a laxative, is up the but and around the corner. Just playing its 3 degrees.
