Question

hydrogen ion concentration in mol/L in solution ph =5.4 will be​

Answer 1

Answer:

hydrogen ion concentration of solution with pH 5.4 is 4 X 10⁻⁶ mol/l

Explanation:

Given

pH = 5.4

[H⁺] = ??

Solution

As

pH = 5.4

- log [H⁺]  =  5.4

[H⁺] = Antilog - 5.4

[H⁺] = 10⁻⁵°⁴

we can write it as

[H⁺] = 10⁻⁶ . 10⁺⁰°⁶.......................(i)

As log 4 = 0.6

thus 4 =  10⁰°⁶

from equation (i)

[H⁺] = 4 X 10⁻⁶ mol/l
