Asolution with a ph = 13 has approximately how many moles of oh– ions per liter? how many molecules of h+ would this same solution have per liter? a different solution with an h+ concentration of 1.0 × 10–4 would have a ph =

Answer :

(A) The number of moles of ions per liter is, 0.1 moles/L

(B) The number of molecules of ion is,

(C) The pH of the solution will be, 4

Solution for part A :

First we have to calculate the pOH of the solution.

As we know that,

Now we have to calculate the moles of ion per liter.

Solution for part B :

First we have to calculate the ion concentration.

Now we have to calculate the number of molecules of ion

As, 1 mole contains number of molecules of ion

So, moles contains number of molecules of ion

Solution for part C :

it is a good conductor
