Question

2. The pool maintenance man forgot to bring his logarithmic charts, and he needs to raise the amount of hydronium ions, t, in the pool by 0.50. To do this, he can use the graph you created. Use your graph to find the pH level if the amount of hydronium ions is raised to 0.50. Then, convert the logarithmic function into an exponential function using y for the pH. @imqwerty

Answer 1

dont spem is post ;~;

Answer 2

hayhayz we had to locate the points where the pH was 0 and 1 in last question
did you do that?

Answer 3

I think so lol might be right might be wrong but i did put points

Answer 4

to find the point where the \(p_H\) value is 0 and 1

well the \(p_H\) is denoted on the y axis
and the \(t\) is denoted on the x axis

so you just click and drag over the graph and find the points where the y coordinate( the pH value) is 0 and 1
and you note down the corresponding x value
for example- i found out the point where the pH was 0 http://prntscr.com/aabau3
so the point where pH is 0 is (0, 1)

similarly you can find the point where pH is 1
it will be (0.1, 1)

Answer 5

Ok ok i see what you did there

Answer 6

How do I do the next part :)

Answer 7

alright so after raising the hydronium ion concentration it became 0.5

and now you need to find the pH

so we know that the hydronium ion concentration is on x axis
and pH on y axis

so you locate that point on graph where the x coordinate is 0.5
the corresponding y coordinate is the pH. :)

Answer 8

Oh wow youre making this seem so much easier then it sounds so far lol

Answer 9

lol :)
so now we know the pH

after this we need to convert the an exponential function
andddd it says that we mus t use "y" to denote pH.

alright :)
so 1st we write our logarithmic function-

\(p_H= -log_{10}(t)\)

now we replace \(p_H\) with y
so our expression is this-> \(y=-log_{10}(t)\)

now we need to convert it to an exponential function

remember this thing->
IF \(\large \color{oragered}{a=log_b(c)}\)
then-> \(\large \color{orangered}{b^a=c}\)

okay this is our function-
\(y=-log_{10}(t)\)
multiply by -1 both sides to get this-
\(-y=log_{10}(t)\)

now use that orange thingy to get this-
\(10^{-y}=t\)

:) this is your logarithmic function converted into an exponential function

Answer 10

Okay im following.. there is one more part I need help with if you dont mind :)

Answer 11

:) okay i can help
