Question

if p= m then, ____ alkalinities are present​

Answer 1

Explanation:

From these three alkalinities it is sufficient to measure M and P alkalinity only; the caustic alkalinity is then given by 2P – M.

...

M Alkalinity and P Alkalinity.

(1a) M alkalinity = Alk = total alkalinity (endpoint: CO2 EP )

(1b) P alkalinity = carbonate alkalinity (endpoint: HCO3- EP )

(1c) caustic alkalinity (endpoint: CO3-2 EP )
