Question

Please show all work!! Thank you!! :)

A 0.6841 gram sample of an antacid is weighed out and then 50.00 mL of 0.098 M HCL is added to the antacid.

A. Calculate the moles of acid added to the antacid.

B. The solution is titrated to its endpoint. What color is the solution at the endpoint this week?

c. To reach the endpoint, 22.83 mL of 0.1032 M NaOH are required. How many moles of base are used for the back titration?

d. How many moles of acid were neutralized by the antacid?

e. Based on this data, what is the acid consuming capacity (ACC) of the antacid (moles/g)?
