An aqueous solution has a hydrogen-ion concentration of 5.0 x 10^-6M. What is the pH of the solution?
A: 6.3
B: 6.0
C: 5.0
D: 5.3

Respuesta :

Answer: 5.3

Explanation:

i took the test and got it correct, hope this helps :)

An aqueous solution has a hydrogen-ion concentration of 5.0 × 10⁻⁶. The pH of the solution is 5.3.

Hence, Option (D) is correct answer.

What is pH ?

pH is used to measure whether the substance is acidic, basic or neutral and the range is 0-14.

How to find the pH of a solution ?

To calculate the pH of solution we need to know the concentration of hydrogen ion that is H⁺ ion.

It is expressed as:

pH = - log [H⁺ (aq)]

    = - log [5.0 × 10⁻⁶]

     = - [log 5 + log 10⁻⁶]             [log a × b = log a + log b]

     = - [log 5 - 6 log 10]             [log aˣ = x]

     = -[log 5 - 6 × 1]                    [ log 10 = 1]

     = - [0.698 - 6]

     = - [-5.3]

     = 5.3

Thus from the above conclusion we can say that An aqueous solution has a hydrogen-ion concentration of 5.0 × 10⁻⁶. The pH of the solution is 5.3.

Hence, Option (D) is correct answer.
