Why starch paste is added to boiling water in preparing starch solution in break point chlorination?
Starch paste is added to boiling water in preparing a starch solution for breakpoint chlorination to ensure even dispersion and prevent clumping. The heat helps to gelatinize the starch, allowing it to dissolve properly and form a smooth solution, which is essential for accurate testing of chlorine levels. This process enhances the visibility of the color change when iodine is introduced, indicating the presence of residual chlorine. Overall, it facilitates precise monitoring of water disinfection effectiveness.
What happens with you put starch and cold water together?

Why does starch paste thicken when stirred?
Starch paste thickens when stirred due to the mechanical agitation that breaks down the starch granules, causing them to swell and release amylose and amylopectin into the liquid. This process, known as gelatinization, increases the viscosity of the mixture as the starch molecules absorb water and form a gel-like structure. The stirring action enhances the distribution of heat and moisture, further promoting the thickening effect.
