In basic spherification techniques, which calcium salt is commonly used to supply Ca2+ ions that cause sodium alginate to gel and form spheres?

Options:

Calcium chloride (CaCl2)
Calcium carbonate (CaCO3)
Calcium oxide (CaO)
Calcium sulfate (CaSO4)

Correct answer: Calcium chloride (CaCl2)

Explanation: Calcium chloride (CaCl2) dissociates to release Ca2+ ions that crosslink sodium alginate chains to form a gel; such spherification methods were popularized in molecular gastronomy around the early 2000s.
