Question

What are the concentrations of h3o+ and oh− in tomatoes that have a ph of 4.10?

Answer 1

1,258×10-10

Step-by-step explanation:

Answer 2

Answer : The concentration of
`H_3O^+` and
`OH^-` are
`7.94* 10^(-5)` and
`1.258* 10^(-10)` respectively.

Solution : Given,

pH = 4.10

pH : pH is defined as the negative logarithm of hydronium ion concentration.

Formula used :
`pH=-log[H_3O^+]`

First we have to calculate the hydronium ion concentration by using pH formula.

`4.10=-log[H_3O^+]`

`[H_3O^+]=antilog(-4.10)`

`[H_3O^+]=7.94* 10^(-5)`

Now we have to calculate the pOH.

As we know,
`pH+pOH=14`

`4.10+pOH=14`

`pOH=9.9`

Now we have to calculate the hydroxide ion concentration.

`pOH=-log[OH^-]`

`9.9=-log[OH^-]`

`[OH^-]=antilog(-9.9)`

`[OH^-]=1.258* 10^(-10)`

Therefore, the concentration of
`H_3O^+` and
`OH^-` are
`7.94* 10^(-5)` and
`1.258* 10^(-10)` respectively.
