Question

What is the [h+] concentration in a urine sample that has a ph of 6?

Answer 1

Answer:

           1.0 × 10⁻⁶ M       (Option-A)

Solution:

Data Given:

                  pH  =  6

                  [H⁺]  =  ?

Formula Used:

As we know pH is given as,

                                  pH  = -log [H⁺]

and,

                                  [H⁺]  =  10^-pH    ----- (1)

Putting value of pH in eq. 1,

                                  [H⁺]  =  10⁻⁶                                       ∴ 10  =  Antilog

                                  [H⁺]  =  1.0 × 10⁻⁶ M

Answer 2

Answer:

The correct answer is option a.

Explanation:

The pH of the solution is defined as negative logarithm of hydrogen ions concentration in its aqueous solution.

$pH=-\log [H^+]$

The pH of the urine sample = pH = 6

Concentration of hydrogen ion in the urine sample = $[H^+]$

$6=-\log[H^+]$

$[H^+]=10^{-6} M$

Hence, the correct answer is option a.
