Answer : The correct option is, (C) 1.7
Explanation :
First we have to calculate the moles of and
.
The balanced chemical reaction will be:
0.01 mole of dissociate to give 0.01 mole of
ion and 0.02 mole of
ion
and
0.03 mole of dissociate to give 0.03 mole of
ion and 0.03 mole of
ion
That means,
0.02 moles of ion neutralize by 0.02 moles of
ion.
The excess moles of ion = 0.03 - 0.02 = 0.01 mole
Total volume of solution = 100 + 300 = 400 ml = 0.4 L
Now we have to calculate the concentration of ion.
Now we have to calculate the pH of the solution.
Therefore, the pH of the solution is, 1.7
