    Cyanuric chloride: Introduction Cyanuric chloride has been known7 since 1827 when it was considered to be the trichloride of cyanogen. Liebig was determined its composition. Liebig prepared it by passing chlorine over dry potassium thiocyanate. Converted impure cyanogen chloride to cyanuric chloride by Serullas7. Reactions take place with sunlight. The cyanuric chloride was considered to be an isomer rather than the trimer of cyanogen chloride for some years. 1 As late as 1867, the trimer to

    What you can safely say is that because the metallic oxides and silicon dioxide have giant structures, the melting and boiling points are all high. Electrical conductivity Silicon dioxide doesn't have any mobile electrons or ions - so it doesn't conduct electricity either as a solid or a liquid. The molecular oxides Phosphorus, sulphur and chlorine all form oxides which consist of molecules. Some of these molecules are fairly simple - others are polymeric. We are just going

    Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions, and write net ionic equations for precipitation reactions, as well as to identify spectator ions, perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate, copper (II) nitrate, iron (III) nitrate, barium

    In this lab, lab 4.3 Comparing the Concentrations of Saturated Solutions, we set out to find and compare the solubilities of two solids in water. In addition, we tested if solubility is a characteristic property of a solid in a given liquid. This lab allowed us to test and use a reliable way to measure the solubility of a solid. This lab can be replicated for any solid with the same procedure, thus it gives us a method to calculate solubility. The two solids we tested in this experiment were NaCl

    An Introduction to Qualitative Analysis Purpose:  Tests the ions of Mg2+, Ca2+, Sr2+, and Ba2+,  and identify them separately. By using these  observations, identify the unknown ion. Then tests  the ions of SO42-, CO32-, Cl-, and I-,identify them separately, and use the observation to identify the unknown.  Procedure Part I - Qualitative Analysis of Group 2 Elements  Mix 0.02M K2CrO4 with each Mg(NO3)2, Ca(NO3)2, Sr(NO3)2 and  Ba(NO3)2 together. Secondly, mix 0.1M (NH4)2C2O4 instead

    However, water has the ability to dissociate many salts and ionic compounds. This is called dissolving. When NaCl is added to water, it dissociates into the ions; Na+ and Cl- . The positive sodium ions are surrounded by the slightly negatively charged part of water molecules (i.e. oxygen) in the water molecules and the negative chlorine ions are surrounded by the slightly positively charged part of water molecules (i.e. the hydrogen). The kinetic energy of the sodium chloride molecules increase with

    RESULTS & DISCUSSION The experiment used qualitative analysis to determine two cations in an unknown solution. In Part A, identified either silver or lead that was interfused into the metal nitrate salts solution. In Part B, calcium or barium would appear. In Part C, another method of qualitative analysis was performed by cation flame tests. The various metal chloride solutions would be used to observed and recorded the colored flame of each species. The goal was to practice qualitative strategies
