Common Ions and Their Charges - ScienceGeeknet
Common Ions and Their Charges A mastery of the common ions, their formulas and their charges, is essential to success in AP Chemistry You are expected to know all of these ions on the first day of class, when I will give you a quiz on them You will always be allowed a periodic table, which makes indentifying the ions on the left “automatic ”

Laboratory 7: Chemical Equilibrium
The solution also contains the ions K + and NO 3-, but these are merely spectator ions and do not participate in this reaction The relative amounts of the various ions participating in the reaction can be judged from the color of the solution since in neutral or slightly acidic solutions, Fe +3 is light yellow, NCS-is colorless, and FeNCS2+ is
FORMULAS AND NOMENCLATURE OF IONIC AND COVALENT COMPOUNDS
Polyatomic Ions Polyatomic ions are ions that are composed of two or more atoms that are linked by covalent bonds, but that still have a net deficiency or surplus of electrons, resulting in an overall charge on the group A metal plus a polyatomic ion yields an ionic compound Formulas and Names of Some Polyatomic Ions NH 4 + ammonium CO 3 2

2 Consider the ions of potassium (K) and sulfur (S) Write chemical formulas for all possible ionic compounds involving these ions, using the simplest ratio(s) of potassium (K) and sulfur (S) Keep in mind that the sum of the charges in an ionic compound must equal zero 3 Consider the ions of iron (Fe) and sulfur (S)
Solubility of Salts - K
K sp values The greater the K sp the more ions are in solution, hence the greater the molar solubility However, you can only directly compare salts that give equivalent numbers of ions in solution For example, you can compare the K sp ’s of all salts with a 1:1 ion ratio like: AgBr, BaSO 4 etc Or, you could compare K sp

ions, omitting the non-reacting species (spectator ions), K+(aq) and NO 3 (aq) 1 point is earned for a valid explanation (b) Explain the purpose of drying and weighing the filter paper with the precipitate three times The filter paper and precipitate must be dried several times (to a constant mass) to ensure that all the water has been
