March 2013 Identify and Unknown Ionic Compound ILI#3 Abstract: In this laboratory investigation‚ 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution. The students performed an experiment in which the reactions between each substance were compared to the unknown solution #1’s reactions and the color of each solution was compared to help find the unknown #1. The unknown ionic compound was identified to be Zinc Sulfate

Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are soluble or insoluble we can check the chart in the textbook

Tetrapyrrole compounds: chlorophyll and heme groups By Erwin Lim 1. Tetrapyrrole compounds A tetrapyrrole compound is a chemical group that consists of four pyrroles that are joined together by covalent bonds‚ forming a porphyrin ring. They are naturally occurring pigments‚ which are used in many biological processes (Berg‚ 2009). The basic structure of a tetrapyrrole is as seen in Figure 1‚ while the basic structure of a pyrrole is as seen in Figure 2. Figure 1.Tetrapyrrole Compound (Berg‚ 2009)

Premium Teeth Meaning of life Oak
is an atom or a molecule with a positive or a negative charge due to the loss or gain of one or more electrons. Ionic solids are salts (such as NaCl) that are held together by a strong force of attraction between ions of opposite charge. Molecules are the smallest physical units of an element or a (chemical) compound. Ionic solids are also known as salts because salts are ionic compounds that are formed from a reaction between an acid and a base. Hydrates are inorganic salts which contain specific

COORDINATION COMPOUNDS: * FLEXIDENTATE CHARACTER OF POLYDENTATE LIGANDS; * Poly dentate ligands have flexi dentate character in the sense that all donors atoms may not form coordinate bonds with the central metal atom or ion. For example; EDTA which is the hexa dentate ligand also acts as tetra dentate or penta dentate in certain complexes. Similarly sulphate ion‚ which is a bi dentate ligand‚ also acts as a mono dentate ligand in certain complexes‚ e.g. in [Co(SO4)(NH3)5]Cl. * LABILE
