Question

What is the pH of an aqueous solution with a hydrogen ion concentration of [H+]=6.9×10−6 M? pH=

Answer 1

pH = - log [H+] so the pH of the solution is 5.16

pH= - log [6.9 X 10 ^-6 ]

so type into your calculator 6.9 EE - 6 on a simple TI calculator, then press log

Note: if you are using a graphing calculator, you press log first, input the number followed by ) , then press enter

It's all about how to use your calculator.
