A500.0 ml buffer solution is 0.10 m benzoic acid and 0.10 m sodium benzoate has an initial ph of 4.19. what is the ph of the buffersolution upon addition of 0.010 mol ofnaoh? the kafor benzoic acid is 6.5 • 10-5

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
