Water (Villastellone)

1. IC CARMAGNOLA 3

2. Chemicals of the First Class of
our Secondary School present:
the unit of measurement of ph
and the hardness of Carmagnola’s
water…

3. It says if the water is acid or basic;
Naturally the process in solution has a PH between 6 and 9;
This parameter underlines an alteration of the examinated water status.
Our law: considered by D.Lgs. 31/2001: it is in the indicator parameters, with
a value between 6,5 and 9,5
CONCENTRATION of HYDROGEN’S IONS (PH)

4. ALL READY WITH
OUR
LITMUS TEST!!!
The pH of the water is
neutral!

5. TOTAL HARDNESS (SALTS CONTAINED)
It is expressed in milligrams of carbonato of calcium CaCO3 present in
a litre of water. The Unit of measurement is the Grado Francese (°f)
The water is classified in base of their hardnesss:
- Light and sweetly water: hardness under 15°f
- On average hard water : hardness between 15 and 30°f
- Hard water: hardness over 30°f
Our law: considered by D.Lgs. 31/2001: it is in the indicator parameters , with
a value between 15 and 50°f.
