Hello!
datos: Molarity = 
ps: The ionization constant of the sulfuric acid is strong and completely dissociates in water, so the pH will be:
![pH = - log\:[H_3O^+]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5BH_3O%5E%2B%5D%20)
![pH = - log\:[1*10^{-4}]](https://tex.z-dn.net/?f=%20pH%20%3D%20-%20log%5C%3A%5B1%2A10%5E%7B-4%7D%5D%20)
Note:. The pH <7, then we have an acidic solution.
I Hope this helps, greetings ... DexteR!
Answer:-
0.648 M
Explanation:-
Volume of Ba(OH)2= 34.63ml/1000=0.03463 litre
Number of moles of Ba(OH)2 = 0.3275 M x 0.03463 litre
= 0.01134 moles
Since Ba(OH)2 has 2 OH in its formula,
Number of moles of OH- = 2 x 0.01134=0.02268 moles.
Volume of HCl= 35ml/1000 = 0.035 litre
At the end point number of moles of H+ = number of moles of OH-.
Number of moles of HCL= Concentration of HCl x Volume of HCl
∴ Concentration of HCl = 0.02268 moles/ 0.035 litre
= 0.648 moles/ litre
= 0.648 M
