In general, the radiation heat transfer from one surface to another is the radiation leaving the first surface for the other minus that arriving from the second surface. Radiation heat transfer is mediated by electromagnetic radiation, known as thermal radiation, that arises due to the temperature of a body.

The p K a of hypochlorous acid is 7.530 . A 60.0 mL solution of 0.103 M sodium hypochlorite ( NaOCl ) is titrated with 0.296 M H

IrinaVladis [17]

Answer:

pH of the solution after addition of 8 ml 0,296 molar HCl = 7.94

Explanation:

In this case buffer exist between hypochlorous acid HClO is a weak acid and its conjugate base hypochlorite ion ClO⁻ which are deliver to the solution by NaOCl ( sodium hypochlorite ).

The salt is completely dissociate

[NaOCl] = [ClO⁻]

Using Henderson equation to find pH of this buffer

pH = pKa + log $\frac{[Conjugate base]}{[Acid]}$

or, = 7.53 + log $\frac{60 X 0.103}{8 X 0.296}$

or, = 7.53 + 0.4

or, = 7.94
