DKFLSDFKLFKJ | Acid-Base Titration. | kfjhdkjhvdkfj | | April Jowers | 12/19/2012 | DKFJSDKJFHDSKJHF | Introduction In this lab we will use basic titrating skills and techniques in order to titrate HCl. We will also be practicing how to prepare the solution. Using the titration data‚ we can practice our stoichiometric skills and also become more familiar with using lab equipment. Titration is the process of measuring the exact volume of a solution of known concentration that is

1. Put your safety goggles and lab coat on. 2. Gather all the necessary materials in order to conduct this experiment such as boiled water‚ distilled water‚ calcium chloride‚ distilled water‚ glycerin‚ test tubes‚ nails‚ test tube rack‚ graduated cylinders‚ tongs‚ scoopula‚ erasable marker and parafilm. 3. With the erasable marker‚ label the ten test tubes from 1 to 10. 4. For Test Tube 1‚ drop an iron nail in it without adding anything else. Place the test tube into the to-be-heated rack (50⁰F)

Nitrate on Pond Water By Claudia Phillips September 6‚ 2014 Block Two INTRODUCTION This lab was designed to study and observe the effects of phosphate and nitrate applied to pond water (1). Phosphorous‚ commonly used in fertilizers‚ is a necessary and vital element for life but can enhance the effects of eutrophication (the over-enrichment of nutrients in water) (2). Nitrate is a common source of food for most algae‚ but too much can make living conditions in water harsh (3). They are

polluted water so the water will have a clarity of 0%. If a filter is built for the polluted water‚ then the waters clarity will be 0% and the pH value will be 7. The purpose for this lab is to get the polluted water to a clarity of 0%. Water pollution is playing a major role in today’s ecosystems because the water is becoming unsafe to live in and unsafe to consume. “Water pollution is any physical or chemical change in water that adversely affects organisms” (Chiras‚ 2015). When the water is dirty

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- Mn2+(aq) + 4H2O Theory:

Determination of Chlorine and Iodine in Water I. Introduction The purpose of this laboratory was to determine the amount of chlorine and iodine in a sample of water by titration using a starch indicator and to standardize a sodium thiosulfate solution. Chlorine is added to municipal water supplies to purify it enough to become safe to drink. Iodine is also added to water when people camp or go hiking in the back country where they cannot bring purified water along. Chlorine and iodine are

Pennsylvania State University Lab Report on Experiment 10- The Chemistry of Natural Waters Introduction What is water hardness? Water is extremely important to all living things and even to non-living things‚ indirectly. Therefore‚ the way water travels and gets to a place is also extremely important because its transportation methods determine the chemicals that get involved and added into the water as it travels. This relates to the hardness of water. The hardness of water is basically caused by the
