generally pH of d.m water i.e. out from mixed bed exchanger is 6-7.5. but the boiler feed water criteria is different. hence before feeding to the boiler again pH and electrolites checked.
The commonest test is to check the electrical conductivity between two electrodes. Pure water has very poor conductivity, but the conductivity improves as more ions are dissolved in it. Sea water has...
the pH scale runs from 1-14. 1 to 6.9 is considered an acid with 1 being the strongest acid and 6.9 being an extremely almost neutal acid. 7 is neutral. 7.1 to 14 is a base with 14 being the...
