Question

a student conducts a volumetric analysis to determine the concentration of an unknown HCl solution. the student adds 25 ml of the unknown acid to a flask and then titrates with 0.101 M NaOH. 21 mL of the NaOH is required to reach the endpoint of the titration. what is the molarity of the hcl solution? a student conducts a volumetric analysis to determine the concentration of an unknown HCl solution. the student adds 25 ml of the unknown acid to a flask and then titrates with 0.101 M NaOH. 21 mL of the NaOH is required to reach the endpoint of the titration. what is the molarity of the hcl solution? a student conducts a volumetric analysis to determine the concentration of an unknown HCl solution. the student adds 25 ml of the unknown acid to a flask and then titrates with 0.101 M NaOH. 21 mL of the NaOH is required to reach the endpoint of the titration. what is the molarity of the hcl solution?

Explanation / Answer

Volume of NaOH solution = 21 ml
Concentration of NaOH solution = 0.101 M

Volume of Unknown HCl solution = 25 ml
Concentration of HCl solution =?

21 ml x 0.101 M = 25 ml x MHCl
MHCl = 0.085 M

Molarity of the HCl solution =  0.085 M
