Question

A) What is the volume of 0.700 M NaOH needed to neutralize the 20.00 mL of 1.30 M HC1 solution? b) The data suggest a different volume was needed to neutralize the HCI. Explain why this may be the case.

Answer 1

And & A) What is the volume of 0.700M Naon needed to neutralize the 20.00mL of 1.30 M HCl Solution ? Sina we knoue Acid + Base salt & H₂O Helt NaOH Nace + H₂O Amount of Hel present in 20mL of 1:30MHO Solution = 1. 30x20 = 26 millimoles of Hel To Neutralize 26 millimoles of hcl Same anout of NaOH needed. So, - Miv, = M2V2 => 1.30X20 = 0.700 XV2 M, and M2 - Ve = 1.30x20 are molare one. 0.700 OF HO and Naolt Viand Uz are => [V2 = 37.14 me their volumes. OF NAOH needed to M2= 0.7oon Neutralize 20 ml 1.30NHO. Ver ? M,= 130M V = 20mL And & B The data Sygest a different volume was needed to neutralize the Hl. Explain why this may be the case -> The different amount of NaOH (volume) meeded because Concentration of Both Acl and Na Olt are not same. Hel os of high concentration and Naop is of love Concentration. Amount of Hl. Present in pere unit volume of te A solution in more than that of Naot solution. This us the reason for different volume of Naot needed.
