Dear Chandan
The reaction involved in the titration is:
Ba(OH)2 + 2HCl -------> BaCl2 + 2H2O
The equation that is used to find the molarity of unknown solutions in titrations is:
M1V1/n1 = M2V2/n2
Where
M1 and M2 are, respectively, the molarities of Ba(OH)2 & HCl solutions.
V1 and V2 are, respectively, the volumes of Ba(OH)2 & HCl solutions.
n1 = Stoichiometric coefficient of Ba(OH)2 = 1
n2 = Stoichiometric coefficient of HCl = 2
Therefore:
molarity of barium hydroxide solution, M1 = (M2V2/n2) x (n1/V1) = (0.1 x 35 / 2) x (1/25) = 0.07 M
