Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions

Sodium was first discovered by Sir Humphrey Davy in 1807. This element is the 11th element found on the periodic table; located in group 1 and period 3. Its chemical symbol is Na and it is classified as a metal. Metals‚ by definition‚ means that they are elements that are luster‚ lose electrons very easily‚ malleable‚ ductile‚ and are great conductors of heat and electricity. Sodium is found in group 1 of the periodic table because the electronegativity of sodium is very low. This allows it to form

Coatings such as zincand tin provideprotection againstcorrosion. Other platedmetals include nickel‚copper‚ and gold. While the electroplating is in progress‚ additionalsalts of the metal to be plated must continually be added to the platingsolution‚ or else the anode must be renewed‚ if it consists of the platingmetal.

Honors Chemistry Period 2 September 22‚ 2013 PRE-LAB Title: Density of Metals – Shot Lab Purpose: The purpose of this lab is to find out the density of different metals using their mass and volume. If the volume and mass for the metals Nickel and Copper are found‚ then we can figure out the density. Materials: Metal shot Plastic rinse bin Electric Balances Calculator Graduated Cylinders Water Wire Gauze Weigh Boats Pre-lab Questions: 1) The volume of the water is 43.0 mL

2. Element X melts in boiling water‚ it fails to react with hydrochloric acid; and 1 cm3 of element X has a mass of 1.8 grams. Is element X a metal or non-metal? Give the reasons for your answer. Element X is most likely a typical non-metal. First of all‚ element X melts in boiling water; non-metals typically have low melting and boiling points. Furthermore‚ element X is unable to react with hydrochloric acid. This greatly indicates that element X is a non-metal as most non-metals fail to

Finite Element Analysis Introduction Finite element analysis (FEA) has become commonplace in recent years‚ and is now the basis of a multibillion dollar per year industry. Numerical solutions to even very complicated stress problems can now be obtained routinely using FEA‚ and the method is so important that even introductory treatments of Mechanics of Materials – such as these modules – should outline its principal features. In spite of the great power of FEA‚ the disadvantages of computer

Are superheavy elements really so unstable that there is no point trying to synthesis new elements? This leads to the question: ‘How does the size of an element affect the stability?’ What are superheavy elements? The scientific term ‘superheavy’ means elements that have an atomic number that is heavier than‚ element 101‚ which is Rutherfordium. As they suffer from radioactive decay when exposed to lighter elements‚ they are not naturally occurring. Meaning‚ scientists can only artificially make
