Answer : The pH of the solution will be 13.63.
Solution:
Moles of hydroxide ions in barium hydroxide solution
Number of moles = (concentration)(volume in liters) ...(1)(1L=1000mL)
<em>2.0 M barium hydroxide in solution</em>
Number of moles of in 2.0 M solution
moles
If One mole of barium hydroxide gives two moles of hydroxide in solution then 0.008 moles will give:
Number of moles of moles
Moles of ions in nitric acid
<em>In 1.00 M nitric acid solution</em>
Moles of nitric acid in 1.0 M solution moles
If one mole of nitric acid will give one moles of ion.
Then 0.010 moles of nitric acid in solution will give :
Number of moles of moles
Since , the reaction will be neutralization reaction, equal number of moles of will neutralize equal number of moles of
So,0.010 moles of will neutralize 0.010 moles of
in the solution
Remaining moles of moles
Concentration of resulting solution
Resulting volume of the solution : 0.004 + 0.010 liters
Calculating by using equation (1).
The pH of the solution will be 13.633.
