3. In Part IV of the Procedure, you added 6M HCl to the Discarded Solutions beaker containing excess NaOH solution. HCl reacts with NaOH as shown in Equation 5. HCl(aq) + NaOH(aq) -NaCl(aq) + H2O(l) (Eq.5) Briefly explain why it would be hazardous to dispose of either your NaOH solution or 6M HCl in the drain, yet it is safe to...

9) What are we removing with the water wash? Why don’t we just
add the sodium bicarbonate directly to the reaction mixture instead
of doing a water wash? 10) Provide the results of the silver
nitrate test.
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCl, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once...

How could you use a precipitation reaction to separate the two metal ions? We could add HF (aq) to obtain a precipitate of AgF (s). We could add more H2O to obtain a precipitate of AgOH(s). We could add HCl (aq) to obtain a precipitate of AgCl (s). o We could add HCl (aq) to obtain a precipitate of NaCl(s).
