Question
**Post Lab Questions** 1. **Classify the following reactions as precipitation, gas evolution, or neutralization reactions.** *Hint: You do not find the products. Look at the reactants only!* | Reactants | Type of Reaction | |--------------------------------|------------------------------| | Pb(NO₃)₂ (aq) + KBr (aq) | | | HNO₃ (aq) + KOH (aq) | | | FeCl₃ (aq) + NaOH (aq) | | | HCl (aq) + AgNO₃ (aq) | | | HBr (aq) + Na₂CO₃ (aq) | | | CaCl₂ (aq) + Na₂CO₃ (aq) | | 2. **For the precipitation reaction, draw a picture of the beaker or test tube after the reaction has occurred. Assume the reaction has had time to settle.** Reaction: CuSO₄ (aq) + 2 NaOH (aq) → Cu(OH)₂ (s) + Na₂SO₄ (aq) **Diagram Explanation:** In the diagram, you should depict a beaker or test tube containing a clear liquid with a solid precipitate that has settled at the bottom. The clear liquid represents the aqueous solution of sodium sulfate (Na₂SO₄), and the solid at the bottom is copper(II) hydroxide (Cu(OH)₂), which is insoluble in water and forms a precipitate.
