electrically uncharged. In this experiment all of the precipitates result from the exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

The Ionic Lattice In most ionic compounds‚ the anions are much larger than the cations‚ and it is the anions which form the crystal array. The smaller cations reside in the holes between the anions. Basic Concepts: 1. Ions are assumed to be charged‚ incompressible‚ nonpolarizable spheres. 2. Ions try to surround themselves with as many ions of opposite charge as closely as possible. Usually in the packing arrangement‚ the cation is just large enough to allow te anions to surround it without

TITLE: Solubility and Thermodynamics PURPOSE: The purpose of the lab was to determine the thermodynamics variables of ∆H‚ ∆S‚ and ∆G for the dissolution reaction of potassium nitrate in water. The solubility of potassium nitrate in mol/L was measured over a range of various temperatures by finding out at what temperature crystallization began for solutions of different molarities. Then‚ the equilibrium constant was calculated and a graphical relationship between the natural logarithm of the

Nicotine and Reaction Time Introduction: Nicotine is a drug‚ nerve poison‚ sedative and also a stimulant. It is said to have stimulating and relaxing effects‚ but it depends on the dosage of nicotine. As it was mentioned above‚ Nicotine is both a stimulant and a sedative; this means that straight after you have ingested nicotine‚ it gives you an adrenaline rush and also helps you to relax afterwards i.e. crash. This means that if I conduct my experiment straight after the smokers have ingested nicotine

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance

Experiment 8 “Lipids” and the purpose of the lab is to become familiar with the properties and reactions of certain lipids called fats or oil. For this lab‚ students are testing the properties and reactions of lipids and soap will be prepared and its properties will be tested. To begin the experiment‚ place 5 mls of water‚ ethyl alcohol‚ chloroform‚ and toluene in to four clean test tubes and add 1 drops of cottonseed oil to each test tube. Shake it and record your observation. To do part B‚ in three
