Hydrochloric acid. HCl, with a concentration of 0.100 M can be purchased from chemical supply houses, and this solution can be used to standardize the solution of a base. If titrating 25.00 mL of a sodium hydroxide solution to the equivalence point requires 29.67 mL of 0.100 M HCI, what is the concentration of the base?
Titration of a 20.0-mL sample of acid rain required 1.7 mL of 0.08 11 M NaOH to reach the end point. If we assume that the acidity of the rain is due to the presence of sulfuric acid, what was the concentration of sulfuric acid in this sample of rain?
Describe in words the titration of an acid with a base. Be sure to use the terms equivalence point, indicator, and end point correctly.
ssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.
Calcium carbonate, CaCO3, can be obtained in a very pure state. Standard solutions of calcium ion are usually prepared by dissolving calcium carbonate in acid. What mass of CaCO3 should be taken to prepare 500. mL of 0.0200 M calcium ion solution?
A sample of solid calcium hydroxide, Ca(OH)2, is allowed to stand in water until a saturated solution is formed. A titration of 75.00 mL of this solution with 5.00102M HCl requires 36.6 mL of the acid to reach the end point. Ca(OH)2(aq)+2HCl(aq)CaCl2(aq)+2H2O(l) What is the molarity?
Lead poisoning has been a hazard for centuries. Some scholars believe that the decline of the Roman Empire can be traced, in part, to high levels of lead in water from containers and pipes, and from wine that was stored in leadglazed containers. If we presume that the typical Roman water supply was saturated with lead carbonate, PbCO3 (Ksp = 7.4 1014), how much lead will a Roman ingest in a year if he or she drinks 1 L/day from the container?
Titration of a 25.00 mL sample of acid rain required 12.4 mL of 0.009879 M NaOH to reach the end point. If we assume that the acidity of the rain is due to the presence of sulfuric acid, what was the concentration (in mol/l and %) of sulfuric acid in this sample of rain?

In the course of various qualitative analysis procedures, the following mixtures are encountered: Ag+ and Mn2+ . Suggest how each mixture might be separated.
A solid sample containing chloride ion is analyzed by argentimetric titration to find the percentage chloride by mass. The procedure involves the preparation of a solution made from primary standard sodium chloride (molar mass = 58.443 g mol-1). Aliquots of NaCl solution will be titrated with silver nitrate solution to accurately determine the AgNO3 concentration. The standardized silver nitrate will be used to titrate aliquots of unknown chloride solution, thus allowing for the determination of the percentage chloride in the original solid sample. To detect the endpoint of the titration the adsorption indicator dichlorofluorescein is used. Please solve for the highlighted portions.
A sample contains BaCl2 plus inert matter. What weight must be taken so that when the solution is titrated with 0.100 AgNO3, the milliliters of titrant will be equal to the percent BaCl2 in the sample?
