Question 147Steam Plants - 1st Asst/Chief

The correct answer is C) dissolved salts from sea contamination. Testing boiler water for chloride content will indicate the amount of dissolved salts, particularly from seawater contamination. Chloride is a common ion found in seawater, and its presence in boiler water can signify that the water has been contaminated with saltwater, which can lead to corrosion and scaling issues in the boiler system. The other options are incorrect because they do not directly relate to the purpose of testing for chloride content. Option A is about total alkalinity, option B is about methyl orange, and option D is about phosphates, none of which are directly indicated by chloride testing.
