Abstract Water “hardness” was analyzed in this experiment‚ through the determination of CaCO3 concentration. This was achieved by the titration of an unknown solution using a standardized 0.1M EDTA‚ and addition of Eriochrome Black T to the unknown‚ to indicate the endpoint of the titration. The average concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The

Chapter 1 INTRODUCTION Rationale of the Study Coffee and Milktea both have legendary past. Milk Tea‚ originally known as Bubble Tea or Pearl Milktea‚ came into existence in Taiwan‚ during the 1980’s. From a tea shop called Chun Shui Tang in Taichung‚ Taiwan. Unlikely the fully loaded pearl milk tea today‚ the oldest form of bubble tea was made by mixing cold black tea with fructose syrup using a shaker. The product was named bubble tea after seeing the layer of foam that ended up on the top of the

Serina Pooja Sowman | Practical 7: Determination of Hardness in Water | | | | | 10/3/2012 | | Aim: To determine the different types of hardness and alkalinity found in the water by titration methods. This is used to calculate the concentrations of calcium and magnesium found in the water. Principles: The hardness of water is determined to provide a measure of the quality of water for household and industrial use. Hard water is not a health hazard. Drinking hard water

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
