Today, calcium metal is usually prepared by electrolysis of fused calcium chloride to which a little calcium fluoride has been added. It is used in alloys with other metals, such as aluminum, lead, or copper; in preparation of other metals, such as thorium and uranium, by reduction; and (like barium) in the manufacture of vacuum tubes to remove residual gases.

Acid-Base Properties of Salts | Boundless Chemistry
In acid – base chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base. Basic salts contain the conjugate base of a weak acid, so when they dissolve in water, they react with water to yield a solution with pH greater than 7.0.

Calcium Bicarbonate - an overview | ScienceDirect Topics
Calcium bicarbonate solution produced under high pressure can spontaneously form calcium carbonate under atmospheric pressure. The problem of bicarbonate biocement produced by the treatment of CaCO 3 or Ca(OH) 2 is its low concentration and instability, so the solution must be produced and stored at elevated partial pressure of CO 2..

Reactions of hydrochloric sulfuric nitric acids with …
REACTION OF ACIDS WITH METALS General word equation: metal + acid ==> a salt + hydrogen The salt, and its name, depends on the metal and acid used in the reaction and the acid is neutralised in the process. e.g. the grey-silvery solid zinc dissolves in hydrochloric acid with effervescence to evolve hydrogen gas and leave a colourless solution of the salt zinc chloride.
