Why does hard water have a higher pH compared to soft water?
Hard water contains more mineral ions, increasing the pH.
Soft water being highly buffered, lowers its pH
Hard water undergoes a chemical reaction that raises its pH.
Hard water is more prone to acidification, resulting in a higher pH.
Most soft water falls between the range of 6-7, while most hard water falls between the range of 7-8. That’s because the minerals in hard water reduce the amount of acid in the water, so when they’re removed, the result is a lower pH level.
