no need for distillation. Next‚ a solubility test was given. When one drop of the unknown liquid was added to about 2 mL of water‚ the sample was tested to be soluble due to the dissolubility between the two compounds. By following the chart that was given on the sheet‚ the pH of the solution was tested. Since the two litmus did not changed color‚ the sample was identify to have a low molecular weight and a neutral substance. Based on the solubility test‚ some possible

Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

Complexometric Determination of Water Hardness by EDTA Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe. Introduction When the water from the rain collects impurities by dissolving the

INFORMATION SERIES Hardness in Groundwater February 2007 What is water hardness? Water hardness is primarily the amount of calcium and magnesium‚ and to a lesser extent‚ iron in the water. Water hardness is measured by adding up the concentrations of calcium‚ magnesium and converting this value to an equivalent concentration of calcium carbonate (CaCO 3 ) in milligrams per litre (mg/L) of water. The Guidelines for Canadian Drinking Water Quality Hardness divide hardness into the following

Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex

Alana Rogers Date of experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble

11th Grade Chemistry Honors Which Type of Water is the Hardest? Hardness is the quality in water that is imparted by the presence of dissolved salts‚ especially calcium and magnesium. Hardness refers to how many mineral particles there are in water. The harder the water is‚ higher the contents of minerals. A geologist is a person who specialized in geologic research and study; a hydrologist is a geologist that studies the circulation‚ distribution‚ and properties of the waters of the earth and
