In a titration experiment, 15.0 mL of 0.10 M Ba(OH)2 is required to titrate a 10.0 mL of an unknown solution of HNO3. Calculate the concentration of the HNO3

Question

solution using the data. 2HNO3 + Ba(OH)2 ® Ba(NO3)2 + 2H2O

Answer 1

2HNO3 + Ba(OH)2 ==> 2H2O + Ba(NO3)2

mols Ba(OH)2 = M x L = ?
From the equation, you know mols HNO3 = twice moles Ba(OH)2
Then M HNO3 = mols HNO3/L HNo3
