A 22.26-mL sample of hydrochloric acid solution requires 35.00 mL of 0.115 M sodium hydroxide for complete neutralization. What is the concentration of the original hydrochloric acid solution?

Solutions

Expert Solution

HCl(aq) + NaOH(aq) -------------> NaCl(aq) + H2O(l)

1 mole    1 mole

HCl                                                            NaOH

M1 =                                                        M2 = 0.115M

V1 =22.26ml                                              V2 = 35ml

n1 = 1                                                         n2 = 1

                  M1V1/n1   =    M2V2/n2

                       M1          =   M2V2n1/V1n2

                                          = 0.115*35*1/22.26*1   = 0.18 M

The concentration of hydrochloric acid = 0.18M
