You have to use a special "color code" paper. Put the paper on the substance. Then use a pH scale to determine the color and that will tell you the pH of the substance.
(You could use this information for a science fair project)
Another way would be to use a pH meter- its more accurate but expensive.

pH<7 -> acidic
pH=7 -> neutral
pH>7 -> basic
The value of [H+] depends on whether it is a strong acid/base (-> total dissociation)
or a weak acid/base (-> need to known Ka/b, the equilibrium constant for dissociation)
That's all there is to it.

The pH can also be used to indirectly determine the concentration of the hydroxide ion in aqueous solutions.

What does substance's pH tell you?
Ph tells you how acidic/basic a solution is. It is a measure of the relative concentrations of H+ ions to OH- ions.
What is pH of a substance?
The pH of a substance tells if it's an acid, neutral, or a base. With all deference to the asker and to the previous answerer, technically substances don't have pH's. Aqueous solutions have pH's, and the pH tells you (on a logarithmic scale) the concentration of H+ (or more precisely H3O+) in that solution. A substance is an acid if it lowers the pH of a solution when it is dissolved. It does this by donating protons (H+'s) to water molecules to create more H3O+. A substance is a base if it increases the pH of a solution by accepting a proton from water molecules to form OH-. H3O+ and OH- are in equilibrium with each other in solution, so the more OH- you create, the less H3O+ will be in solution and the higher the pH. So a better answer to the question is that "The pH of a solution tells you if its an acidic, neutral, or basic solution."
What do indicators tell us?
Indicators are used to tell a person whether or not a chemical is present or what pH a substance may be. Usually an indicator is a strip that is dipped into the substance and will change color based on the presence of a substance or pH.
If the ph of a substance is 11 then that substance is?
If a substance has a PH of 11 then the substance is basic.
What is the pH of a substance?
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
What tells how acidic or basic a substance is?
The Ph
What would a ph of 10 tell you about a substance?
It tells that the substance is basic, as pH is higher than 7.0
The label on a bottle indicates that the substance inside has a pH of 13 this tells you that the substance is?
poison
What does a pH number between 7-14 tells you about the substance?
it means its a basse i thinkk
What does substance's pH tell you?
Ph tells you how acidic/basic a solution is. It is a measure of the relative concentrations of H+ ions to OH- ions.
What does a chemicals PH tell us about the chemical?
It tells about the degree of acidity or alkalinity of a substance. The pH is a measure of the concentration of hydrogen ions present. pH = - log10 [H+] Example: concentration of H+, [H+] = 0.010 M pH = - log10 0.010 = 2 pH = 5 [H+] = 10-5 M = 1 x 10 -5 M pH = 3.5 [H+] = 10-3.5 M = 3.2 x 10-4 M

What is the difference of litmus paper and a pH paper?
pH.paper tells the strength of an acid and alkali and litmus paper tells that whether the substance is an acid or an alkali.
If the ph of a substance is 11 then that substance is?
If a substance has a PH of 11 then the substance is basic.
What is the pH of a substance?

Which is the most acidic pH 2 pH 5 pH 7 or pH 11?
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
