Purpose The purpose of this lab experiment is to observe physical and chemical properties of substances which are also known as chemicals. Procedure For this laboratory experiment I followed the detailed procedures outline in the Labpaq manual by P. Jeschofnig‚ LP-0125-CK-01. (Jeschofnig‚ Peter.‚ Ph.D.‚ "Physical and Chemical Properties." General College Chemistry. Englewood‚ CO: Hands on Lab Inc.‚ 0. 65-71. Print.) First‚ I followed all safety measures as outlined therein. After

-Meniscus is a measurement used for measuring liquids‚ for water and most liquids the line with the center of the meniscus reading in the bottom is used. 6. How would you clean the lab after completion? - Items in labpaq are generally used multiple times. Always clean and return un used items to the bag after completing experiment. -Clean used and left over chemicals with paper and place in a garbage or flush down using enough amount of water

let us know the vinegar have reach a point of neutralization once the vinegar turns pink. We can then calculate the concentration of acetic acid in the vinegar. Procedure: Data: Set up the lab: Take a tick text book and place it on top of the labpaq box to use as a titrator holder. Slip the clamp into the textbook by placing the test tube clamp into the middle of the book. The stop cock tip should be 1-2 cm above the beaker. Use the test tube holder to clamp the 10 mL syringe with an affixed

arrangements using several magnification techniques by way of 10x‚ 40x‚100x oil immersion lenses and a light source. The main purpose was to observe the shapes and arrangements of microbial bacteria and yogurt. Procedure The lab involved self-provided and labpaq materials to perform several exercises to obtain the purpose of the lab. The lab began with the proper identification of all components of the microscope and their functions. This allowed for preparation of the objective of being able to view specimens

Identification of Metallic Ions TITLE: LAB 5.1 IDENTIFICATION OF METALLIC IONS PURPOSE: In this lab we are learning how to observe and perform “flame tests”‚ of alkali and alkaline earth metal ions. We will use basic lab equipment provided in our Labpaq‚ and follow all safety precautions in this lab. From reading the discussion and review‚ we understand that the normal configuration of the electrons is called “the ground state”. We understand that they are in stable condition‚ while at their lowest

EXPERIMENT II: SEPERATION OF A MIXTURE OF SOLIDS PURPOSE: The purpose of this experiment was for me to become familiar with the separation of mixtures and solids and to learn separation techniques based on the chemical properties of a substance. PROCEDURE: Before beginning‚ I set up a data table to record data from the experiment. 1. Separating out the Iron a) I used my digital scale to determine the mass of my weighing dish. b) I emptied the entire mixture of solids from the plastic bag into

safety precautions you needed to follow? If so‚ what were they? The purpose of this exercise is to learn the anatomy and over all composition of how the heart works and the blood flows through the four chambers of the heart. Always follow the Labpaqs MSDS: Material Safety Data Sheet and do all dissection / use in well-ventilated area. Exercise 1: Microscopic Anatomy of Cardiac Muscle Observations Sketch and label your slide in the space provided. Include a description of the structures
