Answer: The water in the pool is acidic
Step-by-step explanation:
The pH level indicates the concentration of hydrogen ions
in a solution and is setted in a scale from 0 (which is acid) to 14 (which is alkaline), being 7 the neutral value.
In this context, the normal pH level in a pool's water must be between 7.2 and 7.6 . So, since this pool's water pH is 6.5 we can say the water is acidic.
It is important to note that this may lead to skin and eyes irritation of the bathers, instability of chlorinated products and corrosion in the metal parts of the pool that are in contact with this water.
