Question

You have five unlabelled bottles that contain one each of the following: NaOH, AgNO3, NaCO3, KI, HCl. Predict the reaction you would expect for each combination of two solutions. Classify each reaction as precipitation (P), acid-base (AB), or no reaction (NR). If the reaction is a precipitation. Look- up and record either the or solubility of the product to determine if a precipitate is likely to Be seen Use a reference to see if the product formed may be colored or have an odor. If no reaction Happens , write NR in the classification line.

Explanation / Answer

NaOH base

AgNO3 Salt

NaNO3 neutral salts

KI neutral salt

HCl acid

Solution MIxed REaction Classification NaOH+AgNo3 NaOH+AgNO3 ----->NaNO3 + AgOH AgOH will precipate out. Precipitation NaOH +Na2CO3 NO REACTION NaOH+KI NaOH +KI ----> KOH+NaI double displacement but it could be taken as No reaction as no ppt occurs. NR NaOH +HCl NaOH+HCl ---> NaCl +H2O Acid-base AgNO3+Na2Co3 AgNO3+Na2CO3 ---> AgCO3+NaNO3 AgNO3+KI AgNO3+KI ----> AgI+KNO3 precipitation AgNO3+HCl AgNo3(aq) + HCl(aq) = AgCl(s) + HNo3(aq) precipitation Na2CO3+KI No reaction NR Na2CO3+HCl Na2CO3+HCL ------> NaHCO3+NaCl NR KI +HCL KI+HCl-----> KCl+HI NR
