In the laboratory, a general chemistry student measured the pH of a 0.426 M aqueous solution of hypochlorous acid to be 3.897. Use the information she obtained to determine the Ka for this acid. Ka(experiment)

The value of the of the acid is :

Explanation:

The pH of the weak acid solution = 3.879

Concentration of hydrogen ions =

Concentration of hypochlorous acid solution = [HClO]= 0.426 M

Initially:

0.426 M     0       0

At equilibrium

(0.426-0.0001321)M             0.0001321 M               0.0001321 M

The expression of will be given as;

The value of the of the acid is :

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
