glucose in water is colloid or true solution
Glucose in water is colloid because it is a heterogeneous system. Particle size of solute differentiates between colloid and true solution. True Solution is a homogeneous mixture of two or more substances having particle size less than 1 nm. Particles of true solution cannot be filtered through filter paper, parchment paper or animal membrane. Appearance of true solution is transparent while colloid is heterogeneous with particle size 1 to 1000 nm. Appearance of colloid is translucent.
