Is the brown colour in a river a colloid or solution or suspension or an emulsion?
A suspension is a mixture between two substances, one of which is finely divided and dispersed in the other. Common suspensions include sand in water, dust in air, and droplets of oil in air. Particles in a suspension are larger than those in a solutions; they are visible under a microscope and can often be seen with the naked eye. Particles in a suspension will settle out if the suspension is allowed to stand undisturbed. Many particles of a suspension can be separated through a filter. An example of a simple suspension would be flour in water, or sand in water.

What is the theoretical achromatic point of salivary amylase?
If we add salivary amylase to any solution ( eg:iodine solution) the colour of solution changes to blue.THE TIME TAKEN BY THE SALIVARY AMYLASE TO CHANGE ITS(iodine solution) COLOUR TO BLUE IS CALLED ACROMATIC POINT OF SALIVARY AMYLASE. ie, the time upto which the solution is colourless and after that it gains blue colour.
