WebSep 13, 2024 · PhD stands for Doctor of Philosophy. This is one of the highest level academic degrees that can be awarded. PhD is an abbreviation of the Latin term (Ph)ilosophiae (D)octor. Traditionally the term ‘philosophy’ does not refer to the subject but its original Greek meaning which roughly translates to ‘lover of wisdom’. WebExperimental in this sense means "based on physical evidence". This experimental parameter is called "the pKa". The pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. It may be a larger, positive number, such as 30 or 50.
