3.42 grams of Ba(OH)2 is placed in a flask, dissolved in water, and titrated with an HCI solution. It is found that 25.0mL of the HCI solution is required to just neutralize the Ba(OH)2. What is the molarity of the HCI solution?

Answer 1

Ba(OH)2 + 2HCl ==> 2H2O + BaCl2
mols Ba(OH)2 = M x L = ?
Convert mols Ba(OH)2 to mols HCl.
M HCl = mols HCl/L HCl
