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.

the answer would be a

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
