grams of an unknown diprotic acid that was dissociated in distilled water. Shown is the pH versus the volume in milliliters of 0.1 M NaOH‚ a strong base‚ added to the solution. The initial pH reading of the solution was a pH of 2.60. Although the pH of the ½ equivalence point was unknown‚ it could be estimated by halving the volume of NaOH used at the first equivalence point. At the first equivalence point‚ 13.63 milliliters of NaOH had been added to the unknown acid solution. Once divided by two

ability to identify metals is an extremely important one. With this ability‚ we can correctly assign different traits‚ and use the metal in its most suitable environment. This is important to many industries‚ where metals play an increasingly large role. Determining the identity of the metal is paramount to determining what conditions to use the metal under. This seemly simple task is‚ however‚ can be quite complex‚ as there are many ways by which one can identify a metal‚ each with varying amounts

unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then use a solution containing permanganate ion‚ MnO4-‚ to oxidize this Fe2+ to Fe3+ ion. The percent of iron in the sample will be calculated from the amount of permanganate needed to oxidize fully all the Fe2+ ions. A solution of permanganate ion in sulfuric acid efficiently oxidizes Fe2+ to Fe3+ MnO4- + 5 Fe2+ + 8 H+ ( Mn2+ + 5 Fe3+ + 4

What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

SCIENTIFIC PAPER CHEMICAL PERIODICITY MARIE JOE A. ALTERADO JUNE 31‚ 2013 CPE32 AUGUST 7‚ 2013 GROUP NO. 1 ENGR. IMELDA C. GALERA ABSTRACT The chemical periodicity was demonstrated by using different samples of Group IA‚ IIA and IVA elements. Each of the samples was placed in a test tubes and the physical state‚ color‚ and appearance was identified. The solubility of the element was tested through the use of water. The Group IIA Metal Oxides was tested

compound that combines with metal ions to form stable ring structures. It is used to reduce the concentration of free metal ion in solution by complexing it. From the Greek term “chela” that means “the great claw” of the lobster or other crustaceans‚ chelate‚ root word for “chelating”‚ suggests the way in which an organic compound “clamps” onto the cationic element‚ which it chelates. In order for a compound to be called a true chelating agent‚ it must have certain chemical characteristics. This

Chemical Periodicity ------------------------------------------------- ABSTRACT The experiment chemical periodicity shows the properties and reactions belonging to group IA‚ IIA‚ and IVA. Proper procedures and observations were done to determine the solubility‚ physical state‚ color‚ and appearance of the compounds namely Li2CO3‚ Na2CO3‚ K2CO3‚ CaCO3‚ and BaCO3. The results shows that Li2CO3‚ Na2CO3‚ K2CO3 were soluble in water‚ while MgCO3‚ CaCO3‚and BaCO3 were not soluble. All of these compounds
