Purpose The purpose of this exercise is to learn aseptic technique procedures and there importance and also to learn to isolate colonies using the streak plate technique. Introduction Bacteria are inoculated (introduced) and cultured (grown) in the laboratory for test studies to determine their morphology (the shape‚ size‚ arrangement‚ and internal structures) and pathology (ability to cause disease). Inoculation has to be performed without adding other microbes or contaminants. Aseptic (sterile) technique

Lab #16: Gravimetric Analysis of Metal Carbonate Introduction: In this laboratory the identity of group 1 metal Carbonate is determined gravimetrically using a double replacement precipitation reaction. Concepts: Double-Replacement reaction Gravimetric analysis. Background: The identity of group 1 metal M is determined by analyzing an unknown Group 1 metal carbonate‚ M2CO3. There are 3 main reactions in this lab: 1. Equation 1: M2CO3 (s) → 2M+ (aq) + CO32- (aq) 2. Equation 2: Ca2+

Metal bar D(lead) has a identity of 11.36‚ in the experimental density +/- uncertainty bar D is 11.2+/- 0.6 g/mL. The theoretical density information was founded in General Chemistry Laboratory Manual for CSU Bakersfield‚ CHEM 211‚ 3rd ed. Buschhaus‚ M. 2015. Each experimental identification described was strongly supported by there experimental densities +/- uncertainty and by only being off by 0.06. Both results come out in range of

CHAPTER I INTRODUCTION Background of the Study The use of plants for remedies has long been in existence and is among the most attractive sources for developing drugs (Bukantis et al.‚ 1980). Any part of plant can be considered as herbs including leaves roots‚ flower‚ seeds‚ resins‚ leaf sheath‚ bark‚ inner bark (cambium)‚ berries and sometimes the pericarp or other portion (Holetz et al.‚ 2002). Most primates depend heavily on the leaves‚ fruits‚ and flowers of tropical plants to meet their nutritional

operation Laboratory rules 1) Prepare a lesson carnestly before the experiment. Clarify the related basic principle‚ sequence of the operation‚ and safety measures in the experiment. 2) Put on the working clothes before entering the laboratory. Record the experimental phenomena and data. 3) Keep the floor neat. Don’t throw anything into the water trough so as to avoid stops up. 4) After every experiment‚ the students being on duty shall take responsibility for cleaning up the laboratory‚ inspecing
