If 24.83 cm3 of 0.15 M NaOH is titrated to its end point with 39.45 cm3
of HCl, what is the molarity of the HCl?
of HCl, what is the molarity of the HCl?
0.094 M
0.150 M
0.940 M
1.500 M
Spiegazione
NaOH + HCl → NaCl + H2O moles ratio = 1/1
↔ (MaVa) / Mb x 39.45 = 0.094
↔ (MaVa) / Mb x 39.45 = 0.094
