why not maintain Ph 7.0 in Boiler because 7 Ph is not acidic and not basic.

Answer Posted / er_nillu

According to Le-chatelier's principal the equillibrium of reaction depends up on pressure and tepmperature at which it is going to takes place.Therefore at neutral point of hydrogen ions concentration (which is responsible for pH) shifts from 7 (7 is the value of pH at atmospheric condition) slightly 8 to 8.5. Simillerly it will shift below 7 at temp below atm temp.
