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.

The mass has escaped into a gas which you can not see so the law stays true.
