All chemical reactants in the following reactions are completely ionized in aqueous solutions. Complete and balance the molecular chemical reactions. Indicate the physical state of each product in brackets following the chemical symbols for the products. Use the solubility rules found in your chemistry lecture text to predict when a precipitate results from the reaction. If an Arrhenius acid-base reaction occurs, one of the products should be water. None of the reactions are redox reactions. If no reaction is expected from combining the reactants, write NR. After you have completed the experiment, compare your answers from the prelaboratory assignment to the answers obtained after your laboratory observations. Al. CO(NO3)2(aq) + NaOH(aq) A2.
