Question

Instructor: Ewa Zajac, PhD In acid and sodium acetate are mixed; the total ionic reaction is points): H(aq) + Cl(aq) + Na* (ng) + C2H2O2 (ag) - HCH,02(+ Nav + C a. What type of reaction is taking place? b. What are the spectator ions? c. Write the balanced conventional equation: d. Write the balanced net ionic equation: e. What evidence would you likely observe that a reaction has taken place? 5. Given the following data determine the relative activities of the metals from eas series for Ca, Cd, Mg, and Ni (10 points). a. Identify each metal as more active or less active: Cu (s) + 2AgNO3 (aq) + 2Ag (s) + Cu(NO3)2 (aq) Fe(s) + CuSO4 (aq) → FeSO4 (aq) + Cu () Fe(s) + Zn(NO3)2 (aq) → no reaction b. Using the data from the first part of this problem, determine the activity Mg, and Ni. Dediat a lab

Answer 1

a. Double displacement reaction

b. Cl^-, Na⁺

c. HCl_(aq) + NaC₂H₃O_2(aq)$\rightarrow$ C₂H₄O_2(aq) + NaCl_(aq)

d. H⁺_(aq) + C₂H₃O₂^-_(aq) $\rightarrow$ C₂H₄O_2(aq)

e. The change in pH. An increase due to formation of acetic acid which is a weaker acid than HCl
