The pH level, P, of a liquid can be determined from the hydronium ion (H3O+) concentration, c, using the equation P = –log(c). If the pH level of grape juice is 3.3, what is the hydronium ion concentration

Sagot :

MrRoyal

The equation [tex]P = -\log(c)[/tex] is an illustration of logarithms. The hydronium ion concentration is approximately [tex]0.0005012[/tex]

Given that:

[tex]P = -\log(c)[/tex]

When the pH level is 3.3; it means that:

[tex]P = 3.3[/tex]

So, we have:

[tex]3.3 = -\log(c)[/tex]

Divide both sides by -1

[tex]-3.3 = \log(c)[/tex]

Take antilog of both sides

[tex]10^{-3.3} = c[/tex]

So, we have:

[tex]c = 10^{-3.3}[/tex]

[tex]c = 0.00050118723[/tex]

Approximate

[tex]c = 0.0005012[/tex]

Hence, the hydronium ion concentration is approximately [tex]0.0005012[/tex]

Answer:

The correct answer would be 5.01 x 10^-4

Explanation:

Not only did I take the test and get it right, BUT, P = -log(c) aka 3.3 = -log(c), c is equal to 0.00050118, and the expanded form of 5.01 x 10^-4 is 0.000501...
