Find the pH of a 0.0000734 M solution of HI

pH of the HI solution =4.13 .

Explanation:

0.0000734 M concentration of Hl is the same as saying that 7.34 *10-5 moles of H+ ions have been added to solution.  

pH of HI = -log[H+]

The -log[0.0000734] =4.1343.

pH of the HI solution =4.13.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
