* Pure water is neutral: Pure water has a pH of 7, which is neutral. This means it has an equal balance of hydrogen ions (H+) and hydroxide ions (OH-).
* Boiling doesn't change the balance: While boiling water drives off dissolved gases (like CO2), it doesn't alter the fundamental chemical balance between H+ and OH- ions.
* Slight changes are possible: In some cases, if the water is contaminated with dissolved minerals or other substances, boiling might cause a slight shift in pH. However, these changes are usually minimal and temporary.
In summary: Boiling water mainly affects its temperature and removes dissolved gases, but it doesn't significantly change its pH.
