Question

equal volume of solution with ph 4 and ph 10 are mixed. what will be the approximate ph of final solution​

Answer 1

Resultant solution is neutral therefore the pH of the solution is 7.

Step-by-step explanation:

Given data:

pH 4 = acidic in nature

pH 10 = basic in nature

Concentration of H+ ions

[H+] = 10^-4 M

Concentration of [OH-] ions

pOH = 4  [OH-] = 10^-4

            H+ + OH- ⇆     H2O    [Since K = 10^14]

Conc.  10^-4   10^-4

Vol.      VL       VL

Mole    10^-4 V   10^-4 V

             0            0         10^-4 V

• All H+ and OH- ions are completely consumed.
• Resultant solution is neutral therefore the pH of the solution is 7.
