need to be broken • To conduct electricity there must something charged that can move (ions or electrons). Technically this is called a mobile charged species • To dissolve in a particular solvent the substance must interact with the solvent 2) Types of Bonding ▪ Ionic bonding – metals transfer electrons to non-metals producing positive metal ions and negative non-metal ions. An ionic bond is an electrostatic attraction between oppositely charged ions. Dot-cross diagrams show outer electrons

Select a blue or green filter. 2) While you are waiting‚ prepare a results table with TIME in seconds and ABSORBANCE (in relative units). You are going to read the absorbance after 15‚ 30‚ 45 seconds‚ etc. until you have about 9 or 10 readings. 3) Fill a sample tube with distilled
