8 of 17 pH and pOH are related to the normality of acids and bases. The table below gives normalities of pH and pOH units. pH Acid (normality of H) Alkaline (normality of OH) pOH 0 1.0 0.000,000,000,000,01 14 1 0.1 0.000,000,000,000,1 13 2 0.01 0.000,000,000,001 12 3 0.001 0.000,000,000,01 11 4 0.0001 0.000,000,000,1 10 5 0.00001 0.000,000,001 9 6 0.000001 0.000,000,01 8 7 0.000,000,1 0.000,000,1 7 8 0.000,000,01 0.000001 6 9 0.000,000,001 0.00001 5 10 0.000,000,000,1 0.0001 4 11 0.000,000,000,01 0.001 3 12 0.000,000,000,001 0.01 2 13 0.000,000,000,000,1 0.1 1 14 0.000,000,000,000,01 1.0 0 The following is the range of pH commonly encountered in soils in the U.S. pH 5.5 6.0 6.5 7.0

Unformatted text preview: 7.5 8.0 8.5 Strongly acid Medium acid Slightly acid Very slightly acid Very slightly alkaline Slightly alkaline Medium alkaline Strongly alkaline B. Exponents and Logarithms Since calculation of pH involved the use of logarithms the following is a refresher on exponents and logarithms: y * y * y = y 3 ; A A 1 = A A 1 = A 1 A 1 = 2 A 1 0.1 = 10 1 = 10-1 ; 0.01 = 100 1 = 2 10 1 = 10-2 (10 N )* (10 M ) = 10 N+M In general, we can always write any number X as another number A raised to a power y, where y need not and usually is not an integral (whole steps). That is, X = A y . The exponent y is called the logarithm of X to the base A and is written as follows: log A x = y...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
