Eggs contain multiple proteins which gel at different temperatures within the yolk and the white, and the temperature determines the gelling time. Egg yolk gelifies, or solidifies, between 65 and 70 Â°C (149 and 158 Â°F). Egg white gels at different temperatures 60 to 73 Â°C (140 to 163 Â°F) â the white contains ovalbumin that sets at the highest temperature. In practice, in many cooking processes the white gels first because it is exposed to higher temperatures for longer.
The various hydrated forms of copper sulfate include trihydrates, pentahydrates and heptahydrates, however, copper sulfate pentahydrate (CuSO4.5H2O), is the most commonly encountered salt which generates while copper sulfate emits moisture when exposed to air .
Zinc sulfate is the inorganic compound with the formula Zn SO4 as well as any of three hydrates. It was historically known as white vitriol . All of the various forms are colorless solids. The heptahydrate is commonly encountered.
