Question

WHAT ARE THE CONCENTRATIONS OF H30+ AND OH- in tomatoes that have pH oh 4.14

Answer 1

DO H30+ FIRST

THEN OH-

Answer 2

so walk me throught the steps

Answer 3

PH = 4.14 it is a acid solution

Answer 4

Ph = 4.14< 7

Answer 5

so what is H30+

Answer 6

ANSWER

Answer 7

is is -.617

Answer 8

is it -log(4.14) to get H30+

I GOT -.617

Answer 9

nnnnnnnoooooo
PH = -log H3O+ and POH = -Log OH-
H3O+ = e -PH and OH- = e-POH
we have ph = 4.14 it is an acid selution so :
H3O+ = e-4.14
POH = 14 - PH = 14-4.14=9.86 so OH- = e-9.86
since we have an acide solution so [H3O+] must be >>>>>>> [OH-]
so we get that because e-4.14 >>> e-9.86
us i know ....... thanks

Answer 10

to find pH from concentration, you take the -log(H3O+)

to find concentration from pH, you have to do the inverse function, use \(10^{-pH}\)

Answer 11

so it is [H30+]=1*10^4.14
and [0H-]=1*10^9.86

Answer 12

IT IS RIGHT

Answer 13

Close. It is 10^-4.14 for [H3O=]

Answer 14

so fore [H30+]=1*10^-4.14

and what about [OH-]=

Answer 15

You will need to calculate the value for [H3O+] first. Can you put that in your calculator?

Answer 16

is it log ( then 10*-4.14)

Answer 17

No, the log cancelled out.
