WebApplications of Chemistry, Water Treatment webpage.) The tests run on boiler water samples are essentially the same as those run on the make-up feedwater, except total phosphate is determined in place of hardness (test 3 on page E14-1). In this experiment, we will run the three chemical tests as they are done aboard ship.
