35.4 mL of HCl is required for the neutralization of a solution containing 0.275 g of sodium hydroxide. The normality of hydrochloric acid is? A. 0.97 N B. 0.142 N C. 0.194 N D. 0.244 N
We know that 1 gm equivalent weight of NaOH = 40gm 40gm of NaOH = 1gm equivalent of NaOH 0.275 gm of NaOH = 1/ 40× 0.275 eq = 1/4× 0.275 × 1000 = 6.88 meq N1V1 = N2V2 N1×35.4= 6.88 N1 = 0.194 Therefore, 0.194 N is the normality of Hcl.
