math question
« on: November 07, 2009, 22:55:42 »
can anyone help me out?

Find the pH of an acidic substance of your choice. Using
> this pH, show how to find the hydrogen ion concentration,
> [H+], of the substance using the formula. Discuss the
> meaning of pH and [H+], the pH scale and why your chosen
> substance is acidic. Use scientific notation or enough
> decimal places so that your answer has at least 3 place
> values. For example, either use 3.44*10-6 or 0.00000344.

you have to pick a substance and determine its PH
then you have to use the formula that they gave you to find out the number of hydrogen ions
then you have to tell them the relativity of your substances' ph and its hydrogen ions

i dont know what number they want you to get whether it is the ratio of hydrogen ions to ph or if its the number of ions after using their formula
