Chapter 7 Topics List: 7.1 Predicting Whether a Reaction Will Occur 7.2 Reactions In Which a Solid Forms 7.3 Describing Reactions in Aqueous Solutions 7.4 Reactions that Form Water: Acids and Bases 7.5 Reactions of Metals with Nonmetals (Oxidation–Reduction) 7.7 Other Ways to Classify Reactions Review Packet 1. What are the six indicators of a chemical reaction? (hint: think back to our Baggie Lab!) a. _________________________________ b. _________________________________ c. _________________________________ d. _________________________________ e. _________________________________ f. _________________________________ 2. Define a precipitation reaction in your own words: ________________________ ________________________________________________________________ ________________________________________________________________ 3. What happens when an ionic compound dissolves in water? ________________________________________________________________ ________________________________________________________________ 4. Describe in your own words how you use a solubility table: _________________ ________________________________________________________________ ________________________________________________________________ 5. Which ions would Ag3PO4 and MgCl2 split up into? (remember: the amount of ions you draw matters!) Draw what this would look like in 2 beakers. 6. CIRCLE the soluble products (aq) and PUT AN X over the insoluble products (s): AgCl Na2SO4 Ba(OH)2 MgOH KNO3 PbSO4 NaCl CaS Ca3(PO4)2 SrCO3 CaSO4 KOH Soluble Exceptions NO3– salts – Na+, K+, NH4+ salts – Cl–, Br–, I– salts When combined with Ag+, Insoluble Hg22+, Pb2+ SO42– salts When combined with Ba2+, Pb2+, Ca2+ – S2–, CO32–, PO43– salts When combined with Na+, OH– salts K+, Ba2+, Ca2+ 7. Predict the products and the states of the products for the following sets of reactants: a. NaCl (aq) + AgNO3 (aq) → _____________ ( ) + _____________ ( ) b. K2SO4 (aq) + NH4Br (aq) → _____________ ( ) + _____________ ( ) ) + ____________ ( ) c. Pb(NO3)2 (aq) + ZnCl2 (aq) → _____________ ( 8. What are the two states of matter that the products will be in if there is an insoluble product that forms? _____________________ and _____________________ 9. When the ionic solute ‍Na2CO3 is dissolved in water, what can you say about the number of potassium ions (Na+) present in the solution compared with the number of phosphate ions (CO32-) in the solution? How do you know? ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ 10.Write the complete and net ionic equations for #7c. a. Complete ionic equation: b. Net ionic equation: 11.What would the net ionic equation look like if we formed two aqueous solutions as our products? ________________________________________________________________ 12.Label the following on the scale below: water, strong base, weak acid, strong acid, weak base. 13.Acids start with ________ and bases end with ________.
