A combination of chemistry and cooking resulted in a chemical process called molecular gastronomy, spherification to encapsulate liquids. A common chemical reaction plays an important role in molecular gastronomy.

An example of this chemical reaction is the reaction to form spherical olive. To make a spherical olive, calcium chloride which dissolves in the olive juice carefully poured into a solution of sodium alginate. When the calcium choride in the olive juice encounter the alginate sodium in the solution, a chemical reaction occurs to form an encapsulating sphere around the juice. Name the chemical reaction and name the product.
