What is the [h+] concentration in a urine sample that has a ph of 6? a.10-6 m b)10-8 m c)106 m d)10-14 m e.6 m?

           1.0 × 10⁻⁶ M       (Option-A)

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

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.

The pH of the urine sample = pH = 6

Concentration of hydrogen ion in the urine sample =

Hence, the correct answer is option a.

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.
