What is the strongest base in the world?
ortho-diethynylbenzene dianionThe title of strongest base in the world belongs to ortho-diethynylbenzene dianion.
This superbase has the strongest proton affinity ever calculated (1843 kJ mol−1), beating out a long-standing contender known as lithium monoxide anion..
Is a pH of 0 possible?
A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0. … Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
What is the lowest pH possible?
-3.6The lowest pH of -3.6 is the lowest known for any water in the environment.
What is the highest pH possible?
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
Is a pH of 14 a strong base?
Strong bases have very high pH values, usually about 12 to 14. Well-known examples of strong bases include caustic soda or sodium hydroxide (NaOH), as well as lye or potassium hydroxide (KOH). Hydroxides of alkali or Group 1 metals are generally strong bases.
Why pH range is not more than 14?
One far end is not more than 1M of hydrogen ions, which results in a pH value of not more than 0. While on the other end is not more than 1M of hydroxide ions which results in a pH value of not more than 14. … The pH value goes out of the 0-14 range when the concentration of the solution exceeds 1M.
What does a pH of 14 mean?
Remember, a pH of 7.0 is neutral. Anything above that (7–14) is basic, and anything below that (0–6) is acidic.
What is a pH of 14?
Detailed Description. pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Why can pH be negative?
In practice, any acid that yields a concentration of hydrogen ions with a molarity greater than 1 will be calculated to have a negative pH. … This is because glass pH electrodes suffer from a defect called ‘acid error’ which causes them to measure a higher pH than the real pH.
At what pH in the mouth is tooth decay faster?
When the pH in the mouth falls below 5.5, tooth decay starts. Bacteria present in the mouth produce acid by degradation of sugar and food particles which remain in the mouth after eating. The acid produced in the mouth attack the enamel thereby, creating tooth decay. Was this answer helpful?
