These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production haze is defined as the percentage of light that is deflected more than 2.5Â° from the incoming light direction.
Measures the turbidity or cloudiness of a solution. 2. Turbidity is caused by formation of antigen-antibody complexes resulting in the formation of a. precipitate, the more antigen or antibody present, the greater the turbidity.
