Water contains dissolved carbon dioxide, which reacts with water to form carbonic acid.
CO2 + H2O --> H2CO3 --> H+ + HCO3-
The presence of CO2 acidifies the water. Boiling water removes the CO2, which brings the pH closer to neutral.

interior the tip this could be your answer however you have no longer have been given adequate information to make that determination yet. touch you community water branch and get a readout of what's on your water. this might contain chemical components, minerals, hardness, ph and different products. in case you water smells that's a situation. Your water shouldn't scent. you may wish a water softener and/or a opposite Osmosis equipment however in simple terms approximately for all time the water you have is ideal to a brilliant form of fish. you purely ought to understand what your water parameters are and purchase fish that tournament this properly. in case you have very very difficult water evaluate including some salt and going brackish or you ranges could be suited for Lake Tanganykan fish from Africa, or if the ranges are a splash decrease than this possibly imperative American fish or Lake Malawi fish. All of those come from very difficult water factors. in case you water is particularly undesirable then i might circulate the RO path.

You don't want to contaminate the end product of HCL with another substance, like bacteria, otherwise it would not be "standardized"--making of a solution of definite strength so that it may be used for comparison and in tests.

davidsoldh have the right answer. Dissolved CO2 is removed when you boil the water and this is necessary because CO2 reacts with water forming H2CO3 that can affect slightly the pH of water and consequently, your analysis results.
Good luck!

The other answers ring true, but what you really want to get rid of are the dissolved calcium phosphate, magnesium phosphate, and sodium chloride present in tap water (as well as a host of other more minute amounts of trace dissolved inorganic salts).
