Juice Balls: The Science of Spherifiion | Science Project

(This is because sodium citrate can bind to, or chelate, calcium, and prevent the calcium from participating in the spherifiion reaction, shown in Equation 1.) In this food science project, you will investigate how changing the pH of an acidic food, by adding sodium citrate, affects the ability of the food to undergo spherifiion.

Acid Mine Drainage: Chemistry - COTF

Acid Mine Drainage: Chemistry Acid mine drainage impacts stream and river ecosystems through acidity, ferric ion (Fe 3+) precipitation, oxygen depletion, and release of heavy metals associated with coal and metal mining, such as aluminum (Al 3+), zinc (Zn 2+), and manganese (Mn 2+).. When mineral deposits that contain sulfides are mined, they have the potential to produce acid mine drainage.

And if amounts of reagent are precisely adjusted, the water’s alkalinity will be reduced to the theoretical solubility applicable to the CaCO 3 + Mg (OH) 2 system which ranges from 2 to 3°F under normal temperature and concentration conditions.. However, this limit M-alk. figure may be increased in practice when dissolved impurities are present (e.g. organic acids, ammonium, phosphates, etc.).

Spherifiion Class

Gels form when a calcium salt is added to a solution of sodium alginate in water. The gel forms by chemical reaction, the calcium displaces the sodium from the alginate, holds the long alginate molecules together and a gel is the result. No heat is required and the gels do not melt when heated. The gel coating is formed inside the droplet.
