Report Questions 1. Approximately 1 mL of two clear, colorless solutions-0.1 M Ba(NO3)2and 0.1 M Na2SO4- were combined. Upon mixing, a thick, milky white precipitate formed. After centrifugation, the solution above the precipitate was found to be clear and colorless. Based on these observations, determine if a reaction occurred. If so, write the balanced chemical equation and net ionic equation for the reaction. 2. Predict if a reaction would occur when solutions of 0.1 M Al(NO3)2and 0.1 M KI are combined. Explain...
