Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability

strong reducing agents; thus few iodometric determinations. (2) As mentioned earlier‚ iodometry involves the oxidation of iodide ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution. (2) For example in this experiement‚ the analyte that was used was copper in the form of CuSO4•H2O. It was strong enough to oxidize iodide ions to Iodine. The analyte was needed to be isolated

What is Magnesium chloride(MgCl2)? What is it used for and why? What does it look like? Magnesium chloride is the name of a chemical formula of MG CL two. This is a salt and they are a typical ion halide. halides are very soluble to water. magnesium chloride is used for deicing on highways in sidewalks and also parking lots it is a good source of de-icing. The color that it appears is white or colorless crystalline solid. What is magnesium or what is chloride? whare are they located? You can find

Tap Dance in America According to Funk & Wagnalls New World Encyclopedia‚ “ tap dance [is a] style of American theatrical dance‚ distinguished by percussive footwork‚ [which] marks out precise rhythmic patterns on the floor.” Also‚ “Tap is an exciting form of dance in which dancers wear special shoes equipped with metal taps. Tap dancers use their feet like drums to create rhythmic patterns and timely beats‚” Treva Bedinghaus‚ graduated from Holli Barron ’s School of Performing Arts and The

HC2O4−. A salt with this anion is sometimes called an acid oxalate‚ monobasic oxalate‚ or hydrogen oxalate. The equilibrium constant (Ka) for loss of the first proton is 5.37×10−2 (pKa = 1.27). The loss of the second proton‚ which yields the oxalate ion has an equilibrium constant of 5.25×10−5 (pKa = 4.28). These values imply that‚ in solutions with neutral pH‚ there is no oxalic acid‚ and only trace amounts of hydrogen oxalate.[1] The literature is often unclear on the distinction between H2C2O4‚

Determination of Percent Potassium & Percent Iron in an Iron Oxalate Salt by Ion Exchange Introduction: This experiment involves determining both the percent potassium (K) and iron (Fe) in a single titration after passing a solution containing a known mass of complex salt through an ion exchange column. Ion Exchange: Certain materials called ion exchange resins consist of rather large molecules which contain ions that can be displaced. The resins are solids‚ insoluble in water‚ usually granular

Preparation of t-Butyl-Chloride March 8 & 15‚ 2012 Theory: Alkyl halides can be synthesized when alcohols react with hydrogen halides. An alkyl halide is a halogen-substituted alkane‚ and a hydrogen halide is a compound consisting of a hydrogen bonded to a halogen (H-X). Alkyl halides are classified as primary‚ secondary‚ or tertiary depending on the number of alkyl substituents directly attached to the carbon bearing the halogen atom. The purpose of this laboratory experiment was to prepare
