Marisol Camacho AP Chemistry Per. 1-2 10/31/12 Titration Lab Titrations are a very useful method of discovering the amount or concentration of unknown substances. The method is very well suited towards acid-base reactions. Titrations are often used in industry to analyze products to be sold. In this lab‚ standardizations will be done in the first two experiments and then titration analysis in the third. Standardization of a base (NaOH) using a primary standard (KHP) Standardization

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

LAB 3.Ø.Ø: do ions combine in definite ratios PURPOSE The purpose of this investigation is to determine whether ions combine in definite ratios or not. To observe‚ and create a table of the different ions. QUESTION If copper (II) sulfate when mixed with sodium carbonate at different quantities combine to form ions in definite ratios. HYPOTHESIS / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any
