Based on the values you calculated above, which antacid is the strongest / weakest on a single-dose basis? Please explain.
Moles base in one dose
Mass of one dose
Moles/gram for one dose Maalox
Based on the values you calculated above, which antacid is the strongest / weakest on a by-weight (mass) basis? Please explain.
What might you have used in the above experiment in order to see a visible color change in the solution? At what pH would the solution have been neutral?
If you had walked into the lab, only to discover that you only had 0.1 M sulfuric acid available to run you tests, how might this have affected your calculations? Why?
Balance the following reaction.
Al(OH)3 + HCl AlCl3 + H2O
FDA major findings report and summary.
Please show calculations for questions #1 and #2 here.
