Titrimetric analysis of antacid tablets pre-lab queries 1 predict the reaction products for the following antacids with stomach acid, hcl g antacid by titration . In this lab, both forward (direct) and back (indirect) titration methods are used to ascertain the strength of the antacid forward titration titrates the acid directly into an aqueous solution of the antacid, using an indicator to signify the end point. The analysis you will perform is called a back-titration and it is described briefly below: the chemistry: various commercial products are available for the relief of heartburn and indigestion.
An acid-base titration is a method in chemistry that allows quantitative analysis of the concentration of an unknown acid or base solution it makes use of the neutralization reaction that occurs between acids and bases, and that we know how acids and bases will react if we know their formula. Titration will be used to determine the number of moles of h+ neutralized per gram of antacid in the “back-titration,” a portion of antacid will be mixed with an excess of hcl.
