The term originates with Søren Sørensen, where 'p' abbreviates German potenz for power or exponent and 'H' stands for hydrogen, marking the negative base-10 logarithm of [H+].

Usage tips

  • Spanish conversation usually treats pH as a numeric technical value, so speakers typically state the number (for example "el pH es 7") rather than a descriptive adjective.
