pH in Nemeth or UEB

[LaVerne Blaasse]

Could you please tell me should pH - which is a measure of the Hydrogen ion concentration of a solution, therefore, should pH be in Nemeth within a UEB transcription. Thank you so much!

Thank you for the question, LaVerne!

To the best of our current understanding, pH is a "chemical abbreviation" and so should be transcribed in UEB in narrative text. See page 4 of the Provisional Guidance for Chemistry Notation Using Nemeth in UEB Contexts (March 2017), which includes the following:

When chemical abbreviations and acronyms appear in narrative context, code switching is unnecessary.

Section 9 of the Braille Code for Chemical Notation deals with abbreviations, and says "Single letters and combinations of letters used as 'shorthand' names of chemical matter are common in chemistry."

Braille on!
