Logarithmic functions and logic and reasoning

Logarithmic Functions Assignment Booklet 7 The pH of a solution can be determined using the formula pH = -log | H* , where H* is the hydrogen ion concentration in the solution. a. The hydrogen ion concentration of a solution is 0.008 mol/L. Calculate the pH of the solution, to the nearest tenth. (1 mark) b . A baking soda solution has a pH of 8.9. Algebraically determine the hydrogen ion concentration of this solution. Show all your work and express your answer in scientific notation to the nearest tenth.
