BIUXXE BEITT Balanced chemical equation (including states of matter) Reactant copper(t) sulfate and sodium hydroxide hydrochloric acid and sodium hydroxide sodium sulfide and silver nitrate potassium iodide and lead (1) nitrate lead (1) nitrate and silver nitrate hydrochloric acid and sodium carbonate sodium carbonate and copper(li) sulfate (0.6pts) Discussion - Question 1 (0.6pts) Based on your observations, explain why the method used to analyze solutions in Part B of this experiment is NOT a good way to test for Na* or NO," Normalt

Answer 1

1) CuSO4(aq) + 2 NaOH(aq) -------------> Cu(OH)2(s) + Na2SO4 (aq)

2)HCl(aq) + NaOH(aq) --------------> NaCl(aq) + H2O(l)

3)Na2S (aq) + 2AgNO3(aq) -----.> Ag2S(s) +2 NaNO3(aq)

4)2KI(aq) + Pb(NO3)2(aq) ----------> PbI2(s) + 2KNO3(aq)

5) Pb(NO3)2(aq) + AgNO3(aq) --------> no reaction

6)2HCl (aq) + Na2Co3(aq) ----------> 2NaCl(aq) + CO2(g) + H2O(l)

7)Na2Co3(aq) + CuSO4(aq) -----------> CuCO3(s) + Na2SO4(aq)

8) All sodium and nitrate salts are soluble in water.
