pH test is basically done for checking the acidic nature of
any liquid. pH value lies between 1 to 12 to 14 ( i am not
very sure about the upper limit), If the pH value is in
between 1 to 6, then the liquid is considered as ACIDIC.
And if the value is greater then 7, then the liquid is
BASIC. Above all odds, if the value comes to be exact 7,
then it is NEUTRAL (like water).

Answer / thirumoorthy

PH values lies between 1 to 14. if the values is in the
range of below 7,that is acitic substance,if it is greater
than 7 upto 14 that is base. Thae value is 7 that is salt.
so ph test is imporatnt in pumps
