Basic command TOT

[Zhaoyang]

Hi, all,

I want to obtain the total molality of an element, but I get different results from TOT("K"), TOT("K+") and TOT("K(1)"). Does anyone know the reason? Any help will be appreciated.

Best regards,
Zhaoyang

The argument of TOT is either an element or an element redox state. For potassium, only TOT("K") is defined. For PHREEQC, elements are named with capital letter followed by zero or more lower case letters, so K+ is not an element name. No redox state K(1) is defined in any database that I know of.

For example, K, C, C(-4), C(4), S, and S(6) would be legitimate arguments for TOT.
