Question

Calculation of Hydrogen Ion Concentration from pH What is the H1 concentration of a solution with pH of (a) 3.82; (b) 6.52; (c) 11.11?

Answer 1

To calculate the hydrogen ion concentration from pH, use the equation [H3O+] = 10^-pH. The hydrogen ion concentration for pH values of 3.82, 6.52, and 11.11 is 1.5 x 10^-4 M, 2.5 x 10^-7 M, and 7.9 x 10^-12 M, respectively.

Step-by-step explanation:

To calculate the hydrogen ion concentration from pH, you can use the equation:

[H3O+] = 10-pH

Using this equation, we can calculate the hydrogen ion concentration for each given pH:

(a) [H3O+] = 10-3.82 = 1.5 x 10-4 M

(b) [H3O+] = 10-6.52 = 2.5 x 10-7 M

(c) [H3O+] = 10-11.11 = 7.9 x 10-12 M

Answer 2

a) 1.5 x 10^-4

b) 3.2 x 10^-2

c) 7.76 x 10^-12

Step-by-step explanation:

Since pH = - log (H+)

For A,

3.82 = - log (H+)

(H+) = Antilog (-3.82)

H+ = 1.5 x 10^-4

For B,

6.52 = - log (H+)

(H+) = Antilog (-6.52)

H+ = 3.2 x 10^-2

For C,

11.11 = - log (H+)

(H+) = Antilog (-11.11)

H+ = 7.76 x 10^-12

Thus, the hydrogen ion concentration of a, b and c are 1.5 x 10^-4, 3.2 x 10^-2, and 7.76 x 10^-12 respectively.
