Water is the "universal solvent"
B. Water (l)
C. Gas (g)
NaCl (aq) + AgNO3 (aq) NaNO3 (aq) + AgCl (s)
Na+(aq) + Cl- (aq) + Ag+ (aq) + NO3-(aq) Na+ (aq) + NO3- (aq) + AgCl (s)
From the previous example:
Cl- + Ag+AgCl (s)
Aqueous solutions of potassium iodide and silver nitrate are mixed, forming the precipitate silver iodide.
See white board for solution!
HCl (aq) + KOH (aq) H2O (l) + KCl (aq)
H+(aq) + OH-(aq) H2O (l)
Sulfuric acid (H2SO4) and aqueous potassium hydroxide react to produce water and potassium sulfate.
Na2S (aq) + HCl (aq) NaCl (aq) + H2S (g)
Sulfuric acid and aqueous rubidium sulfide with production of hydrogen sulfide gas
