Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

The chemical element copper‚ with Atomic Number 29‚ has been extensively used for thousands of years because of several primary properties that have dictated its use throughout history. Among them we can count durability‚ strength and‚ as a semi-noble metal‚ good resistance to corrosion. With a hardness of 3 on the Mohs scale‚ pure copper is relatively soft and malleable‚ which makes it an easy metal to work with. Analyses of artefacts from lithic civilizations have shown that native copper had not

The book COPPER SUN by Sharon M. Draper. Is an interesting story of a girl‚ named Amari‚ who lived in a nice village‚ with her family and friends until‚ she was kidnapped and sold into slavery. She has many emotions in this book. But I chose a few that I thought were the most important. Which are‚ frightened and happiness. One of the main emotions was frightened/scared. At the beginning of the book‚ Amari’s village was attacked. I know this because in the text it says. “Amari knew she should

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

Determination of Empirical Formula: Preparation of a Copper Sulphide. Aim The aim of the experiment was to determine the empirical formula of sulphide of copper and to make sure that an amount of copper metal reacted with elemental sulphur‚ Eq. 1. To be able to calculate the empirical formula of copper sulphide‚ the mass (grams) of copper has to be known and the mass (grams) of copper sulphide after the reaction. Copper‚ chemical formula Cu‚ is a known metal with a red-brown colour
