180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water, the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions, write balanced equations, and to write net ionic equations for

and Chlorine. Group 1 Physical properties Soft metals are sodium, lithium and potassium that are well cut with a knife. The shiny, silver colour freshly cut surface quickly to a dull grey as the metal reacts with water and oxygen in the air. The reactions are stored in oil and they are pieces of metal. The sodium is a shiny surface that discolours quickly than lithium. Potassium will be made quicker than sodium. This will then show the reactivity increasing in the metals as we get down the group.
energy is needed to break the strong bonds (ionic or covalent) operating in three dimensions. The oxides of phosphorus, sulphur and chlorine consist of individual molecules - some small and simple; others polymeric. The attractive forces between these molecules will be van der Waals dispersion and dipole-dipole interactions. These vary in size depending on the size, shape and polarity of the various molecules - but will always be much weaker than the ionic or covalent bonds you need to break in a giant
with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. Ionic bonding is a crucial topic to understand within general chemistry reactions. Covalent bonding is a root within Organic and Biochemistry that needs to be understood in order to fully understand the theories and concepts discussed in both forms of chemistry. What content in the reading may be used to extend thinking? The similarities and differences between covalent and ionic bonding can be used
lab is to learn to demonstrate a double-replacement reaction of ionic compounds. To accomplish this, two ionic compounds will be mixed together and the product will precipitate out of solution. In this procedure, the product must be precipitated out of the solution and then weighed. For this lab, lead (II) nitrate (Pb(NO3)2) and potassium chromate (K2CrO4) will be reacted together to demonstrate double replacement reaction between 2 ionic compounds. This was shown when chromate replaced the
Chemical compounds are made up of at least two elements that are bonded together in a fixed mass ratio that can only be split apart by chemical means. And a mixture is a substance created by merging at least two different materials with no chemical reaction. Also compounds can only be separated if they are destroyed. But the elements in mixtures can be physically separated from each other easily. Another dissimilarity is that mixtures are usually heterogeneous whereas compounds are always homogeneous
1. What is an ionic bond? Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction. 2. What is a covalent bond? A covalent bond is a bond that occurs when atoms in a molecule share a pair of electrons. For example, “the
March 2, 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour, hardness, melting point, solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours, hard, a
