What will be the final ph when 5.865 ml of 3.412 m naoh is added to 0.5000 l of 1.564 x 10-3 m hcl?

12.5

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

moles of

moles of

According to stoichiometry:  

1 mole of  require 1 mole of

Thus  will combine with    of

Thus of will be left

Thus Molarity of

Putting in the values:

Thus final pH will be 12.5.
