pH is defined only in diluted aqueous solutions. The pH scale, 0 - 14, comes from the dissociation of water (Ka = 10-7). In non-aquous solutions there is no water so this scale is not valid. The only way for direct pH measurement is using a normal pH sensitive electrode (glass, ISFET, enemal, ...) and use a selective electrode sensitive to other compounds in the solution (salts, ions, ...) wich are not affected by pH change.

What is the pH of organic solvents?
That's depend on the type of solvent
What does pH measure directly in a solution?
It measures acidity or alkalinity.
What can be used instead of phenolphthalein to measure pH?
Litmus paper, or other pH papers can measure pH. Many pH test papers can measure specific pH values. There are also instruments called pH meters that can measure pH.
How can you measure the pH of an unknown liquid?
It is very easy to measure pH using a pH meter.
How do you measure the pH of a solution'?
See the Related Questions links for more information about pH.
What is the pH of organic solvents?
That's depend on the type of solvent
What is a change in this can denature a protein?
Temperature, pH, organic solvent, mechanical forces
What does pH measure directly in a solution?
It measures acidity or alkalinity.
What is the universal solvent and its pH category?
The universal solvent is salt since it can dissolve a lot of solutes and salt does not have a pH category
Is POH organic?
pOH is a measure of concentration of OH- ions. pH + pOH = 14 mostly this is used in inorganic chemistry
How are proteins denatured in an organic solvent?
Enzymes and proteins. Denaturation unravels them, ruining their structure and therefore their function.
Is water the solvent in a pH solution?
Yes.
What is the pH schale used for?
pH is a measure of the acidity of an aqueous solution (a solution where water is the solvent). Specifically it is the negative logarithm of the molar concentration of hydrogen ions. A solution with a pH below 7 is acidic while one with a pH above 7 is basic or alkaline. A pH of 7 is neutral. Note that pH is not a measure of the strength of an acid or base, just how acidic or basic a solution is, which depends both on the strength and concentration of the acid/base.

Litmus paper, or other pH papers can measure pH. Many pH test papers can measure specific pH values. There are also instruments called pH meters that can measure pH.
Does coffee powder contain PH?
No, as do no other solids. pH is calculated by measuring the free H3O+ ions in a *aqueous solution,* which by definition is a volume of liquid along with another mass dissolved within where the solvent is H2O. Therefore until you add water, you cannot measure pH.
How can you measure the pH of an unknown liquid?
It is very easy to measure pH using a pH meter.
Why does water exhibit universal solvent?
Because its PH is 7.
