Apple juice has a pH of 2.9, and water has a pH of 7.0. Which substance has a higher concentration of hydronium ions, and how much higher is it? Use the formula , where represents the hydronium ion concentration. has a higher concentration of hydronium ions. Its hydronium ion concentration is times higher than in the other liquid.

Respuesta :

Answer:

(a)

pH of 2.9 has higher concentration

(b)

It is higher by 0.0012599

Step-by-step explanation:

We know  pH formula

[tex]pH=-log[H_3O][/tex]

where

H3O is hydronium concentration

now, we can find concentrations

At pH=2.9:

we can use formula

[tex]pH=-log[H_3O][/tex]

we can plug values

[tex]2.9=-log[H_3O][/tex]

[tex]H_3O=10^{-2.9}[/tex]

[tex]H_3O=0.00126[/tex]

At pH=7:

we can use formula

[tex]pH=-log[H_3O][/tex]

we can plug values

[tex]7=-log[H_3O][/tex]

[tex]H_3O=10^{-7}[/tex]

[tex]H_3O=0.0000001[/tex]

We can see that

pH=2.9 has higher concentration

Difference between concentration is

=0.00126-0.0000001

=0.0012599

Answer:

Apple Juice, and 1.26x10^4

Step-by-step explanation:

I did the work and it would take forever to explain how i got 1.26x10^4 but the more acidic the more H3O+ and the more basic the less H3O and thats

how you get apple juice
