Question

Log help?

Answer 1

The pH level measures the concentration of hydronium ions and can be modeled by the function p(t) = –log10 t. The variable t represents the amount of hydronium ions, and p(t) gives the resulting pH level.
Water at 25 degrees Celsius has a pH of 7. Anything that has a pH lower than 7 is called acidic, while pH's above 7 are basic or alkaline.

1. Create a graph of the pH function. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.

Answer 2

How would I go about creating a graph? I don't expect someone to do the work for me or anything, I'd just like to be pointed in the right direction. Thanks!

Answer 3

\(Ph=-log(c)\) as far as i know, how it's \(-log10t\) ?

Answer 4

I'm sorry I don't understand. What do you mean?

Answer 5

D'oh, I understand now, you don't need to write the (10), i was thinking of it as Log(10 times t)

Answer 6

\(Log(x)=\frac{Ln(x)}{Ln10}\)

Answer 7

i'm sorry, I have to go! thank you for your input
