10. Consider a solution which is 0.10 M in CH3COOH and 0.20 M in NaCH;COO. Which of the
following statements is TRUE?
A. If a small amount of NaOH is added, the pH decreases very slightly.
B. If NaOH is added, the OH" ions react with the CH3CO0' ions.
C. If a small amount of HCl is added, the pH decreases very slightly.
D. If HCl is added, the H* ions react with CH3COOH ions.
TRUE OR FALSE
SURFACE TENSION:
I. A decrease is due to the weakening of the hydrogen bonds of water molecules
II. It is increased when a surfactant is added
III. Soap lowers surface tension of water resulting to the shrinkage of molecules on the surface
29.
A solution containing 90% by volume of alcohol (in water) runs at 1 gal/min into a
100-gal tank of pure water where it is continually mixed. The mixture is withdrawn
at the rate of 1 gal/min. When will it start coming out 50% alcohol?
