What happens when calcium is treated with water?(i) It …

In general, metals form a metal oxide and hydrogen gas and this metal oxide when soluble in water dissolve further forming a metal hydroxide. But some metals form metal hydroxide directly. In the case of calcium, the reaction with water is less violent and hydrogen starts floating on water and bubbles of hydrogen gas will stick to the metal surface.

Grease 101: Lithium or Calcium Sulfonate Grease? - Finol

These soaps take a fatty acid and react it with a metal hydroxide (in this case, calcium hydroxide), to form a calcium soap that is then used to make the grease. However, if they follow the method of creating calcium hydroxide and then add in an additional “short-chain organic complexing acid” you get a calcium-complex soap.
