What does green indicate on the pH scale?
green indicates the pH value of 5-6 which is slightly acidic. for the whole pH color scale go to the reference cited.
What is soap on the Ph scale?
9 to 10
What is washing powder on the pH scale?
10 to 11
how does the pH scale is a mathematical indicator of?
The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.

Is the pH scale linear?
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.
How can you use the litmus paper to develop a pH scale?
After studying the color of litmus at different pH.
What is soap on the Ph scale?

How many numbers are on the pH scale?
10
How much more basic is a solution with a pH of 13 than one with a pH of 10?
Since pH is a logarithmic scale, each increase (or decrease) by 1 means 10 times, so the change of pH in a solution from 10 to 11 would be 10 times, 11 to 12 would be 10 times, and 12 to 13 would be 10 times, and (10)(10)(10) is 1000, so a solution with pH 13 is 1000 times more basic then a solution with pH 10
