many chemical qualities of copper ‚ by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper‚ Concentrated HNO3‚ 6 M NaOH ‚ Bunsen burner‚ 6 M H2SO4‚ Mg ribbon‚ and two test tubes. The techniques used in this lab which is cleaning glassware‚ disposing of chemicals ‚ measuring mass ‚ centrifugation ‚ venting gases‚ and test tube over a “cool” flame.

13. ORGANIC CHEMISTRY IV) ALKYNES SYNOPSIS Alkynes are commonly known as acetylenes. Acetylene is the simplest and important member of the alkyne series. • Alkynes contain – C ≡ C – • General molecular formula of alkynes is CnH2n–2 • Triple bonded carbons are ‘sp’ hybridized and greater s – character is associated with it. • Alkynes will exhibit chain‚ position and functional isomerism. • Their functional isomers are alkadienes and cyclo alkenes. • The minimum number of carbons required to exhibit

is routinely used in analytical chemistry for thequantitative determination of different analytes‚ such as transition metal ions‚ highly conjugated organic compounds‚ and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied. Solutions of transition metal ions can be colored (absorb visible light) because the electrons within the metal atoms can be excited from one electronic state
