Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held

after "Robert Bunsen"‚ is a lab piece equipment that produces a single flame which is used for heating‚sterilization and combustion. Our instructor‚ Dr. Immel‚ provided us with six heavy metals those metals were: Barium‚ Calcium‚ Lithium‚ Potassium‚ Sodium‚ Strontium. My group got a platinum flame loop‚ and decontaminated it with the water beaker filled half way with water. To light the Bunsen burner my group used a striker‚ which Dr. Immel provided. We started off with Barium‚ when Charlotte put it

ground level are the result of the rapid release of energy into the air‚ causing the air to expand faster than the speed of sound. This produces a shock wave‚ a sonic boom. The colors are produced by heating metal salts‚ such as calcium chloride or sodium nitrate‚ that emit characteristic colors. The atoms of each element absorb energy and release it as light of specific colors. The energy absorbed by an atom rearranges its electrons from their lowest-energy state‚ called the ground state‚ up to a

become: K = [Na+]2 [B4O5(OH)42-] The first equilibrium expression and the balanced solubility equilibrium reaction allow us to express either borate ion or sodium ion in terms of the other. So‚ it is possible to determine the constant in terms of either ion. After substituting borax ion in place of the sodium ion‚ ([Na+] = 2 [B4O5(OH)42-] ‚ K = (2 [B4O5(OH)42-] )2 * [B4O5(OH)42-] ) we get: K = 4 [B4O5(OH)42-]3 .

experiment involved the preparation of the working standard Cu(II) solution of specific concentration from CuSO4•5H2O. A standard sodium thiosulfate (Na2S2O3) solution was also prepared to serve as the titrant for the analysis. Proper handling should be administered for this solution since it decomposes into its component ions when it is exposed to acids‚ light‚ and bacteria. Sodium carbonate was added to the solution to act as a preservative. Boiled distilled water was also used in dissolving the crystals

Paraphrasing 1. What is paraphrasing? - A (more or less) free rewording of an expression or text‚ as an explanation‚ clarification and translation. “Paraphrasing‚ or translation with latitude‚ where the author is kept in view…but his words are not as strictly followed as his sense” (John Dryen‚ preface to his translation of Ovid‚ 1680) - An act or result of rewording (Ex. Simplified version of a legal document) - To make a paraphrase: to translate or define loosely

active transport of sodium potassium pumps will decrease dramatically due to the lessened concentration of pumps. If the same transport was run without ATP. it would not work‚ hence justifying that it is not simple diffusion‚ and rather was active transport‚ which requires the use of ATP. No‚ because the two substances are the same in each beaker‚ causing no effect on Na+ transport as they are at equilibrium. The rate of ion transport would increase when the number of sodium-potassium pump proteins
