Question
K = 10-PK, In order to solve for pK you must clear the exponent. Step 1 Take the logarithm of both sides of the equation. log K = log( 10 PK Step 2 Simplify the right side of this equation using the rules. log a" = n log a, and log 10 = 1. log(10 Pk) = -(pKp) log 10 = -pK, The resulting equation is: pK = -log K, -8 b If K = 7.9 x 10 then pK, %3D
