He approximate molar concentration of several chemicals are given. find the ph of each. use the calculator and round to the nearest tenth, if necessary. oven cleaner: [h+] = 10−13 ph = water: [h+] = 0.7 ph = blood: [h+] = 0.4 ph = vinegar: [h+] = 0.0063 ph =

The quantity pH stands for the negative logarithm of the H⁺ ions concentration in a solution. In equation form, pH = -log[H⁺], where [H⁺] is the concentration of hydrogen ion in molarity or moles/liter. Using this definition, the pH of the following substances are:

Oven Cleaner: pH =-log(10⁻¹³ M) = 13
Water: pH = -log(0.0000007 M) = 6.15
Blood: pH = -log(0.00000004 M) = 7.40
Vinegar: pH = -log( 0.0063 M) = 2.2

The measure of the pH is important when it comes to reactions because pH is a strong factor. The net charge of a substance is a result of its pH. This charge is the basis of the degree of intermolecular forces like electrostatic attraction due to difference of charges by the substance and its substrate.
