Experiment 7: Titration of an Antacid
www.bc.eduThe acid neutralizing capacity of a tablet is the amount of hydrochloric acid that it can neutralize. This capacity can be determined by a technique called back-titration. A known amount of antacid is dissolved in an excess of HCl, and then the excess acid is back-titrated with standardized NaOH solution. When the endpoint is reached, the

What is the percent yield if 18.93 g Zn is actually obtained? 10) What mass of aluminum sulfate, in tons, could be formed from the reaction of 1.00 ton of aluminum metal with excess sulfuric acid? 11) Reaction of hydrochloric acid with a sample of zinc hydroxide gave 0.555 g of zinc chloride.

www.bc.edusolution as your ΔH°rxn(5) value. In the neutralization reaction, sodium hydroxide, NaOH, will be present in an excess amount so that even though the solution may be contaminated with Na2CO3 (from the slow absorption of CO2 from the atmosphere), enough OH– will be available to react with all of the hydrochloric acid, HCl, added.

Acid-Base Titration Curves Using a pH Meter
web.gccaz.edu1) hydrochloric acid, HCl(aq) with sodium hydroxide, NaOH(aq); 2) acetic acid, CH 3 COOH(aq) with sodium hydroxide, NaOH(aq). The recorded volume and pH values will generate titration curves that will be used to compare features of the strong acid curve versus the weak acid curve. You will determine the equivalence point volume and pH for both ...
