Waste Disposal Metal Ions
709 wordsQualitative Analysis of The purpose of this experiment is to demonstrate the separation and identification of metal ions based on the insolubility of certain salts. The solubility rules should be taken into account. If a solution dissolves in water, the result contains both cations and anions. Analyzing different ions to discover their nature is the main goal of this experiment. Separation of the cations by testing the differences in solubility of different metal salts is done. Also, identificat...

Volume In Each Burette Number Of Moles Base
530 wordsProblem: When adding acids and bases what is the titration of the two? Amounts of reactants and products in a reaction are commonly investigated in two ways in the lab, gravimetrically (by mass), and volumetric ally (by volume and concentration). Titration is the name we give to the process used to determine the volume of a given solution needed to react with a given mass or volume of a sample. We will use the quantitatively study a neutralization reaction, in a neutralization reaction an acid a...

Distilled Water Color Change
1,564 wordsA theme Carbohydrates INTRODUCTION A theme that we have seen and studied in this class is that a particular form or structure of a molecule plays a significant role in the function of that molecule. Since we are interested in the function of molecules. it helps to study their structure. One of the major classes of organic compounds found in cells are carbohydrates. These carbohydrate are made of carbon, hydrogen, and oxygen in a ratio of 1: 2: 1 respectively with a general formula of X (CH 2 O) ...

Bunsen Burner Hydrochloric Acid
762 wordsThe Problem: I am going to find out how temperature can affect the rate of reaction. Background information: Factors that change the rates of reactions are: ? Temperature? an increase in temperature will make the reaction occur faster. This happens because the particles of that substance move faster when it is heated. Because the particles move faster, they would collide more, making the reaction rate faster. ? Concentration? the increase in concentration, the greater and faster the reaction. Th...

Long Term Effects World War Ii
2,387 wordsRadium is a silver-white, highly radioactive element. It? s atomic number is 88, and it is the heaviest alkali earth metal, having a mass number of 226. 025 (See Figure 1). Radium has at least twenty six isotopes, and all are radioactive (Shriver 1995). Since radium is chemically similar to calcium and magnesium, it is absorbed by the bones of animals. Once in the bones, it emits alpha, beta, and gamma rays (Shriver 1993). These rays shrink or destroy tissues and they are the reason radium is so...
