A correction to my letter published in the Forum of Coast Community News edition 235.
It has been explained to me by a person with superior knowledge on chemistry, that my comment referring to an increase in PH is incorrect and should in fact be pH.
According to this latest advice, reported with my basic knowledge of chemistry, small P signifies minus Log10 of the Hydrogen ion concentration in moles per litre.
I just wonder if Mr Caruana can explain what this means to your readers?
Thank you to your informed and alert reader.
