Answer 4

Aug 4, 2011 - Best Answer: 14 = pH + pOH -log(1.7x10^-9) = pH =(8.77) Calculate the [OH ‾ ], [H+], and the pH of 0.17 M solutions of each of the following ...

Answer 5

according to this it would be a

Answer 6

so C according to that?

Answer 7

No 14 isnt the answer but thats okay :3 thank you

Answer 8

look at everything in the parentheses (8.77)

Answer 9

Do it as i said earlier ? @ilovebmth1234

Answer 10

ohhh lol and yeah but its kinda confusing like i said

Answer 11

did you see what i ws talking about

Answer 12

Answer 13

pH=8.77

Answer 14

when you add them together how would i do that exactly?

Answer 15

type in just the question so you can looh at the first site that comes up i think its like answers .com or something its the very first website

Answer 16

look at the

Answer 17

can you take a screen shot and post it? i cant get on yahoo its blocked :/

Answer 18

how do you do that on a laptop

Answer 19

Answer 20

or try control+ alt + prnt scrn(aka- end)

Answer 21

Do u want me to go thru it again ? @ilovebmth1234

Answer 22

if you make it to where i can understand it

Answer 23

okai

Answer 24

When the concentration of H^+ is given we can't directly use an equation to find the pOH
To find we need to know the pH of the solution.

Answer 25

\[pH = - \log[H ^{+}]\]
\[pH= -\log[1.7 * 10^{-9}]\]

Answer 26

find that value first !

Answer 27

@ilovebmth1234 hey are u working it out ?

Answer 28

okay im trying to

Answer 29

I'll make it easy for u
-log10^-9 = 9
-log1.7 u need to find the log value for 1.7 and put a minus charge in front !

Answer 30

what does -log mean?

Answer 31

log values !!!!!!!!!!!!!!!!!!!!!!!! -log is the minus log value

Answer 32

damn my bad sorry i dont quit understand this like you do v.v

Answer 33

lol so did u find the value now ?

Answer 34

\[-\log10^{-9} = 9\]
\[-\log1.7 = - 0.23\]
\[pH = 9 - 0.23 = 8.77\]

Answer 35

A

Answer 36

or D

Answer 37

pH + pOH = 14
Since pH = 8.77
pOH = 14 - pH = 14 - 8.77
pOH = 5.23

Answer 38

pH is not pOH

Answer 39

right right

Answer 40

so B would be the answer

Answer 41

yes yes

Answer 42

great thanks :3 could you give @james1107 a medal for his help too?

Answer 43

ah yes sure :)
