Question

Calculate the ph resulting from mixing 15. 00 ml of 0. 800 m hio3 (pka = 0. 77) with 45. 00 ml of 0. 0200 m naoh.

Answer 1

By mixing 15.00ml of 0.800m HIO3 (pka = 0.77) with 45.00ml of 0.0200 m NaOh gives a pH = -0.32

The balanced acid-base reaction equation between iodic acid and NaOH is

HIO3 + NaOH -> H20 + NaIO3

What are the functions of buffer system?

In an aqueous solution, a weak Bronsted acid reversibly dissociates to produce weak conjugate bases and hydrogen ions.

The hydrogen ion molarity in the solution and the conjugate pair's molar ratio are related by the K an expression of the weak acid.

The molar ratio will be shifted more in favour of the weak conjugate base if a tiny amount of strong base is added to the weak acid solution. A buffer solution will be produced as a result of the pH of the solution shifting upward.

Hence the pH value is -0.32
