I.Purpose The purpose of this experiment is to separate three components; SiO₂, NaCl, and NH₄Cl through Sublimation, filtration and evaporation to determine the mass and mass percentage of each component. II.Experimental Method EquipmentChemicals Evaporating DishPowdered Mixture A 2 50ml beakerWater Balance Thermometer Bunsen burner III.Raw Data and Calculations Mass of empty evaporating dish76.00g Mass of…

Effect of Temperature on Content of Vitamin C

Introduction A daily intake of Vitamin C is essential for humans. Without it, the disease scurvy develops as sailors, explorers and people during the long winters in the Northern hemisphere found before the time of Captain Cook. The British Navy started giving sailors lime juice to prevent scurvy on long voyages in 1795. Vitamin C…

Qualitative Analysis of Anions

The objective of this experiment was to use qualitative analysis to determine the chemical characteristics of four known anions by systemic confirmatory testing. The chemical characteristics observed were to be used to identify an unknown sample. Sulphuric acid was to be added to a carbonate solution and an effervescent reaction would confirm the presence of…

Experiment 1: Bromination of Acetanilide1 Precautions

Experiment 1: Bromination of Acetanilide1 Precautions: Ethanol is flammable Sodium hypochlorite is an oxidizing agent and releases toxic fumes (handle in fume hood) Acetic acid is corrosive, harmful if inhaled, flammable and can cause burns (handle in fume hood) Gloves are recommended to avoid chemical contact with skin Reaction Scheme: Conversion of acetanilide to p-bromoacetanilide…

Cell Transport Mechanisms and Permeability

Cell Transport Mechanisms and Permeability Purpose The purpose of this lab is to teach me simulating dialysis, simulating facilitated diffusion, simulating osmotic pressure, simulating filtration, and simulating active transport. Hypothesis If I increase the concentration of sodium chloride from 9mM to 18mM in the left beaker, then the rate of diffusion will increase, because concentration…

Experiment 1: Bromination of Acetanilide1 Precautions: Ethanol is flammable Sodium hypochlorite is an oxidizing agent and releases toxic fumes (handle in fume hood) Acetic acid is corrosive, harmful if inhaled, flammable and can cause burns (handle in fume hood) Gloves are recommended to avoid chemical contact with skin Reaction Scheme: Conversion of acetanilide to p-bromoacetanilide…

Determination of Asa Content of Aspirin

Aim: To determine the Molar Concentration of NaOH and HCl acid used in their Standardization processes and to determine the acetylsalicylic acid (ASA) content in Aspirin. Materials/Apparatus: materials used are the same as that outlined in the laboratory procedure prepared by the laboratory instructor. Procedure: The procedure used is the same as that outlined in…

TCC-Travancore cochin chemicals

1. GENERAL INTRODUCTION The main aim of the organizational study is to acquire the knowledge regarding the functional as well as the management aspects of an organization It offers a unique opportunity to students to have hands on experience with industry while still in college. These are major aids in seeking employment after graduation. It…

Agar Cubes Lab Report

Diffusion in agar cubes Introduction: All cells are dependent on a processes called diffusion, which is the movement of a substance from an area of higher concentration to an area of lower concentration. Cells need to obtain certain essential substances, like oxygen, for their survival. The rate of diffusion is said to be dependent upon…

Chemistry project 12th

This reaction is highly exothermic, but that is not why the plastic produced is referred to as “thermoset”. Bakelite is a space-network polymer. Unlike linear and branched polymers, which are composed of long molecules that make them more or less crystalline, space-network polymers are highly and irregularly cross-linked throughout the structure. The sheer extent of…

Star Apple (Chrysophyllum cainito) as an Antiseptic Mouthwash

a. Background of the Study As an effective mouthwash is one that does not only make the breath fresh but also serves as an antiseptic. It should not simply mask the effective mouth odor caused by excessive activity of anaerobic bacteria inhabiting the mouth. There is a need to prevent the increase in the population….

Analysis of Commercial Bleach

Introduction: Many commercial products are effective because they contain oxidizing agents. Some products that contain oxidizing agents are bleaches, hair coloring agents, scouring powders, and toilet bowl cleaners. The most common oxidizing agent in bleaches is sodium hypochlorite, NaClO (sometimes written NaOCl). Commercial bleaches are created by bubbling chlorine gas into a sodium hydroxide solution…

Nvestigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid

Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the…

Neutralization Titrations: The Determination of Soda Ash

I.Purpose: The goal of this experiment is to determine the weight % of Na2CO3 through the preparation of NaOH and HCl standards. The molarity of the standards will be found through titration of KHP for NaOH, HCl vs the known NaOH, and the unknown Soda Ash sample vs the known HCl. II.Equations and Sample Calculations:…
