Question

Pre-lab Questions Predict what would happen if each set of solutions were mixed. In each case, write a balanced equation for any reaction that would occur. Describe what you would observe if you carried out the reaction in the laboratory. If nothing would happen, simply write no reaction. (a) BaC12 (aq)+H2SO4 (aq) (bDAgNOs (aq) + Na2S04 (aą) (c) FeCls (aq) + Na2COs (aq) (d) KOH (aq) HCI (aq) (e) Ag O (s) + HNOs (aq) () BaCOs (s) + HCI (aą)

Answer #1

a) BaCl2(aq) + H2SO4(aq) ------------> BaSO4(s) + 2HCl(aq)

b) 2AgNO3(aq) + Na2SO4(aq) ----------> Ag2SO4(s) + 2NaNO3(aq)

c) 2 FeCl3(aq) + 3 Na2CO3(aq) -------> Fe2(CO3)3(s) + 6 NaCl(aq)

d) KOH(aq) + HCl(aq) --------> KCl(aq) + H2O(l)

e) Ag2O(s) + HNO3(aq) --------> AgNO3(aq) + H2O(l)

f) BaCO3(s) + HCl(aq) ---------->BaCl2(aq) + CO2(g) + H2O(l)
