Some calculators cannot display results of an antilog calculation if the power of 10 is greater than 99. This shortcoming can come into play for determining equilibrium constants of redox reactions , which are sometimes quite large. Solve the following expressions for K : (a) log K = 45.63 , (b) log K = 25.00 , (c) log K = 20.63 . is the relationship among the three expressions and the three answers? How can you use this relationship to solve problems that exceed 10 9 9 even if your calculator will not carry out the calculation directly?

Definition Definition Chemical reactions involving both oxidation and reduction processes. During a redox reaction, electron transfer takes place in such a way that one chemical compound gets reduced and the other gets oxidized.
