Purpose: The purpose of the lab was to observe what happens when two ionic compounds are combined in a small area and to be able to record the type of precipitate that is formed. Background: An ionic compound is formed when ions “transfer‚” or lose or gain electrons. The ions in an ionic compound are held together by ionic bonds in a lattice shaped structured. They are packed tightly together to maximize the attraction between the ions. When two compounds are mixed together‚ they form a precipitate

Procedure Read through the following Procedures and then draw a data table in your notebook to record your observations about any precipitates or gases that form when the two solutions are combined. Remember to include color for precipitates. Examine the reactions against both dark and white backgrounds. If there is no reaction for that combination of solutions write NR (no reaction). Before beginning‚ set up a data table similar to the Data Table: Solubility Rules Table in the Lab Report

Topic 4 - Bonding 4.1 Ionic bonds 4.1.1 Ionic bond: +ve (cations) and -ve (anions) ions are attracted to each other and form a continuous ionic lattice 4.1.2 Group 1 metals form +1 ions‚ group 2 metals form +2 ions‚ metals in group 3 form +3 ions . Examples : Li+‚ Mg2+‚ Al3+. Greater ease of ionisation Li->Cs is due to the increased electron shielding of the nuclear attraction caused by additional inner shells of electrons. The easier atoms are to ionise‚ the more reactive they

Springs push the contacts against the copper ring. The contacts conduct electricity to the copper ring. The copper ring rotates rapidly but does not stick or become worn because the graphite is soft and slippery. Graphite has properties which are ideal for making the contacts in an electric motor.
