The pH of a solution is a measure of the quantity of hydrogen atoms (H) in the solution. It is given by the formula f (x) = - log x.

In the formula, x = [H+], the molar concentration of hydrogen atoms, or the number of moles of hydrogen atoms per liter of solution

The approximate molar concentration of several chemicals are given. Find the pH of each. Use the calculator and round to the nearest tenth, if necessary.

Oven cleaner: [H+] = 10-13 pH =

Water: [H+] = 0.0000007 pH =

Blood: [H+] = 0.00000004 pH =

Vinegar: [H+] = 0.0063 pH =

Camilla Pollard · Answer 2

1. 13

2. 6.2

3. 7.4

4. 2.2

Step-by-step explanation:

1. Over cleaner

[H+] = 10^-13

pH = - log [H+] = - log 10^-13 = 13

2. Water

[H+] = 0.0000007

pH = - log [H+] = - log 0.0000007 = 6.2

3. Blood

[H+] = 0.00000004

pH = - log [H+] = - log 0.00000004 = 7.4

4. Vinegar

[H+] = 0.0063

pH = - log [H+] = - log 0. 0063 = 2.2
