The pH scale is usually stated as between zero and 14 (although negative pH is sometimes included and thus the scale is extended to -1 to 14)
Typical pH's ; battery acid is around zero, household bleach 13, water 7, blood 7.3, urine 6, seawater 8, vinegar 3

What are intervals of pH?
There are no intervals in pH: it is a continuous property, like concentrationbut it has practical limits of about -1 < pH < 15
What limits the pH of the solution?
The concentration of H+ or OH-.
What are the tolerable limits for arterial blood pH?
6.9 to 7.5
Is it possible for an earthquake to be off the scale?
No, because earthquake magnitude scales don't actually have limits!
What are the characteristics of a buffer system?
Buffering system is the physiological system that function to keep pH within normal limits.
What colour is copper sulphate on pH scale?
it is lite green on the scales of PH

What are the levels of Ph scales?
A pH scale ranges from 0-7. 0 to <7, the pH is acidic. At 7, it is neutral. 7 to <14, it is basic
How is the pH scale different from other scales of measurement like the Fahrenheit temperature scale?
pH is a logarithmic scale, so a change of 1 in pH means a change of 10 in the quantity. It is also negative, so as pH increases the measured quantity actuallly goes down. The temperature scales are simply direct scales; all changes mean the same thing and going up means going up.

How do manufacturers determine the limits for the calibration of scales and balances?
I assume you mean the manufacturer while making and selling scales and balances. By the specifications on the equipment they are selling.
Is it possible for an earthquake to be off the scale?
No, because earthquake magnitude scales don't actually have limits!
Strongest base a pH can have?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
Why do semi's need to stop at weight stations on the highway?
All commercial trucks are subject to total vehicle weight limits and also weight limits per axle. The scales are there to enforce these weight limits.
Substances which maintain a body's pH within narrow limits are called what?
Buffers
