✦ Synopsis

In a previous paper (1) it has been shown that silver/silver chloride ion selective electrodes are stable in a simulated pore solution and that the potential of these electrodes is a function of chloride ion activity.This has now been compared with chloride concentrations in the pore water, found using a pressure extraction technique, with chlorides added as sodium chloride to the mix water in concentrations ranging from 0.046Mdm" to 0.46Mdm" to ordinary portland cement pastes with a water cement ratio of 0.45. The results show good correlation between concentration added and activity calculated from electromotive force data, with an activity coefficient of 0.46 ;tr 0.07, which agrees with values calculated in the previous paper.

Chloride analysis was quite easy and salt contents of all butter and margarine samples were found to be less than 2 g NaCl/kg while those of cheese and meat products were above 10 g/kg. Nitrate analysis was not as easy as chloride analysis due to interferences of chloride and organic ions. These int
