Trial 1
Volume of NaOH = 27.02 ml
Concentration of NaOH = 0.2 M
Moles of NaOH = 27.02 x 0.2 / 1000 = 0.005404 Moles
the moles of HCl used = 0.005404 Moles
According to the balanced reaction, equivalent moles of NaOH and HCl required
Volume of acid = 10 ml
Concentration of HCl = 0.005404 x 1000 / 10 = 0.5404 M
Trial 2
Volume of NaOH = 26.59 ml
Concentration of NaOH = 0.2 M
Moles of NaOH = 27.02 x 0.2 / 1000 = 0.005318 Moles
the moles of HCl used = 0.005318 Moles
According to the balanced reaction, equivalent moles of NaOH and HCl required
Volume of acid = 10 ml
Concentration of HCl = 0.005318 x 1000 / 10 = 0.5318 M
Trial 2
Volume of NaOH = 27.25 ml
Concentration of NaOH = 0.2 M
Moles of NaOH = 27.25 x 0.2 / 1000 = 0.00545 Moles
the moles of HCl used = 0.00545 Moles
According to the balanced reaction, equivalent moles of NaOH and HCl required
Volume of acid = 10 ml
Concentration of HCl = 0.00545 x 1000 / 10 = 0.545 M
