The titration of 25.00 mL a 0.125 M HClO4 solution required 21.37 mL of KOH to reach the endpoint. What is the concentration of the KOH

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.

the right answer is c i just did the question.
