The ph of a solution is a measure of the quantity of hydrogen atoms (h) in the solution. it is given by the formula f(x) = −log x.

in the formula, x = [h+], the molar concentration of hydrogen atoms, or the number of moles of hydrogen atoms per liter of solution

oven cleaner: [h+] = 10−13 ph =

water: [h+] = 0.7 ph =

blood: [h+] = 0.4 ph =

vinegar: [h+] = 0.0063 ph =
