Question

EASY MEDAL

5. What is the approximate hydronium ion concentration and hydroxide ion concentration in a cup of tea? Which is higher? (Refer back to the chart of pH if you need to.)

Answer 1

i could use some help here...

Answer 2

do u know the pH of tea?

Answer 3

yeah

Answer 4

and whts that

Answer 5

4-6

Answer 6

now to convert pH into [H+] u need to take anti loge of negative pH

Answer 7

what do you mean "anti loge" ?

Answer 8

*anti-log

Answer 9

ok so how do i take anti log of negative pH

Answer 10

\[[H^+] = 10^{-4}\]
\[[H^+] =1 * 10^{-4}\]

if u find [OH-] then
pOH= 14 - pH
pOH= 14 - 4
pOH= 10
so
\[[OH^+] = 10^{-10}\]
\[[OH^+] =1 * 10^{-10}\]

that means hydronium ion concentration in cup of tea is more

Answer 11

got it??

Answer 12

now u can also prove it for pH=6
