Question

If you have a pH of 3.35, what is the hydrogen ion concentration of the solution?

Answer 1

To calculate the hydrogen ion concentration from a given pH of 3.35, use the formula [H₃O⁺] = 10⁻ pH, which gives a concentration of 4.47 x 10⁻⁴ M, indicating an acidic solution.

Step-by-step explanation:

The question asks us to find the hydrogen ion concentration, given a pH of 3.35. To solve this, we use the formula that relates pH and hydrogen ion concentration:

pH = -log[H₃O⁺]

Rearranging the formula to solve for [H₃O⁺] (the concentration of hydronium ions, which is the same as hydrogen ion concentration in aqueous solutions), we get:

[H₃O⁺] = 10⁻pH

Plugging in the pH value:

[H₃O⁺] = 10⁻³.35

The concentration of hydrogen ions is therefore:

[H₃O⁺] = 4.47 x 10⁻⁴M

This calculation allows us to understand that the given solution is acidic due to a pH less than 7.

Answer 2

Answer: 4.46 x 10^-4M

Step-by-step explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

On the pH scale, readings are from 1 to 14.

- pH values less than 7 are regarded as acidic. So, the solution with pH 3.35 is said to be acidic, and will produce hydrogen ions.

3.35 = -log(H+)

(H+) = Antilog (-3.35)

(H+) = 0.000446M

Place (H+) in standard form

(H+) = 4.46 x 10^-4M

Thus, the concentration of hydrogen ion in the solution with pH 3.35 is 4.46 x 10^-4M
