Question

The pH can be calculated using the equation pH = –log(H+), where H+ is the hydronium ion concentration. Find the hydronium ion concentration of a particular vinegar if the pH level is 2.5.

3.162 x 10–3
3.979 x 10–1
3.162 x 102
9.536 x 103

Answer 1

The pH can be calculated using the equation pH = –log(H+), where H+ is the hydronium ion concentration.

If the pH level is 2.5, we can calculate the hydronium ion concentration by rearranging the equation:

H+ = 10^(-pH)

H+ = 10^(-2.5)

H+ = 3.162 x 10^-3 (Option A)

Therefore, the hydronium ion concentration of the vinegar is 3.162 x 10^-3.

Answer 2

The pH can be calculated using the equation pH = –log(H+), where H+ is the hydronium ion concentration. To find the hydronium ion concentration of a particular vinegar if the pH level is 2.5, we can rearrange this equation to solve for H+:

H+ = 10^-pH

So, if the pH level is 2.5, we can plug in this value into the equation to find the hydronium ion concentration:

H+ = 10^-2.5

H+ = 3.162 x 10^-3

So the hydronium ion concentration of the vinegar is 3.162 x 10^-3.

Option 3.162 x 10^-3 is correct.
