Mixing hydroelectric acid and sodium hydroxide is an example of an exothermic reaction. if you were holding a beaker while this chemical reaction took place, then you would except it to feel?

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.
