Question

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?

Answer 1

The correct answer is option a.

Step-by-step 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.

Answer 2

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
