1) Calculate the [H] in a HC102 solution that has a pH of 3.78.

1.6 X M is the [H] in a HC102 solution that has a pH of 3.78.

Explanation:

Given:

pH of the acid = 3.78

[H+] ion concentration = ?

The dissociation of the acid is shown as:

+ ⇔ HClO2

however, weak acid like HClO2 does not dissociate or ionize completely which causes low hydrogen ion release in the solution.

pH is calculated by applying the formula:

pH = - log [H+]

To calculate the H+ ion concentration the equation will be expressed as:

[H+] =

       =

       = 1.6 X M

The concentration or molarity of the Hydrogen ion in the solution of the acid is  1.6 X M.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
