Dear Scientists,
Just to inquire on the potential of Hydrogen (pH). Is there a solution or substance with pH beyond 14? From primary school to university, we learnt that pH ranges 1 to 14. Where 7 is neutral, 1-6.9 acidic and 8- 14 is alkaline.
Dear Bruce Robin Nyamweha, there are many things to correct in the above statment. The conventional pH range is from 0 to 14. Both above and below this pH range do exist for strongly acidic and basic chemicals, respectively. Please check the following documents. My Regards

Please check; at this forum: https://www.researchgate.net/post/What_is_the_range_of_pH
To the best my knowledge, the limit range of pH scale from 0-14 is mainly applied to water solvent because Kw = [H+][OH-]=10^-14. If you want to change the limit range of pH scale to evaluate stronger acidic or base condition, you need to change the solvent of solution. For example: Methanol, ethanol, and so on.
pH above 14 is not possible which is maximum limit for pH.
