NO!!!

The 'p' in pH is short for 'the negative logarithm to base 10.

The 'H' is for the hydrogen ion concentration.

pH = -log(10)[H+]

Mathemtically inverting

[H^+] = 10^(-pH)

So pH = 1 is equivalenrt to 10^-1 = 0.1

pH = 2 is equivalent to 10^-2 = 0.01

pH = 3 is equivlaanrt to 10^-3 = 0.001

:

pH = 7 is equivalent to 10^-7 = 0.0000001

:

pH = 14 is equivapanet to 10^(-14) = 0.00000000000001

So hopefully you can see that is is decreasing in powers of '10'. on an exponential scale. On a graph this will produce a curve, not a straight line.

No, the pH scale ranges from 0-14 and is considered a logarithmic scale.

What is the difference between a linear scale and a nonlinear scale?

A linear scale is much more simple to use and provides accurate readings it also works faster than the non-linear scale . This scale does not take much work and has equal divisions. In a linear scale, there is an equal amount between each mark; this is the normal kind of scale that is used in most everyday graphs/charts. In a non-linear scale, the difference between each mark is not the same, for example each mark, although the same distance apart on the paper, represents twice the value of the previous mark. Two examples which are met regularly are logarithmic in nature: pH (acid/alkali scale - eg pH balanced shampoo) and dB (deci-Bel - relative loudness of sounds).
