Question

Activity Series: Single Displacement Reactions Prelab: Complete the prelab given in your lab manual for this experiment (page 64-65). Report: You will turn in the data sheets given below. Carefully read the instructions given in each section. Postlab: You will complete the postlab assignment provided in your lab manual (page 66). Your instructor will give you instructions about how to submit your prelab and report. ACTIVITY SERIES DATA Part I. Predictions Table I contains six metals which will be mixed with hydrochloric acid. You are asked to predict whether each of the metals will react to HCl or not. You are asked to point out if you expect to see a vigorous reaction (VR), a slow reaction (SR), or no reaction (NR). Use the activity series provided in your lab manual to help yourself in making such predictions Table 1. Predictions on reactions of HCl with selected metals. Metals Predictions about reaction with HCI Са Mg Fe

Answer 1

Metal	prediction about the reaction with HCl
Ca	Produce dihydrogen gas, Ca (s) + 2 HCl (aq) ----------> CaCl2 (aq) + H2 (g)
Mg	Produce dihydrogen gas, Mg (s) + 2 HCl (aq) ----------> MgCl2 (aq) + H2 (g)
Fe	Produce dihydrogen gas, Fe (s) + 2 HCl (aq) ----------> FeCl2 (aq) + H2 (g)
Cu	No reaction because, Cu cannot replace H+ ion
Zn	Produce dihydrogen gas, Zn (s) + 2 HCl (aq) ----------> ZnCl2 (aq) + H2 (g)
Sn	Produce dihydrogen gas, Sn (s) + 2 HCl (aq) ----------> SnCl2 (aq) + H2 (g)
