Answer to Question #338875 in General Chemistry for Triple X

Question

If 15.65 mL of aq. HCl is required to neutralise 20.00 mL of the sodium carbonate

solution from question 4 above, what is the molarity of the aq. HCl? (Show all steps in

your calculation as set out below.)

(a). Write the reaction equation for the titration.

(b). Calculate the number of moles of Na2CO3 (standard solution) used in the titration.

(c). Using the balanced reaction equation, find the number of moles of HCl that

reacted.

(d). Calculate the molarity of the HCl solution.

Answer 1

There is not enough data in the task, the concentration of Na₂CO₃ is required.
