  • The oxidation state of two Chlorine ion is (2*(-1)) = -2
  • The oxidation state of CaCl2 is (+2-2) = 0

Calcium chloride acidity/alkaline

Calcium chloride is neither acidic nor alkaline. It is a neutral salt. In water, this solid salt creates neutral solution.

Is Calcium chloride odourless?

Calcium chloride is found to be odourless in nature in both solid and liquid state.

Is Calcium chloride paramagnetic?

البارامغناطيسية is the magnetic effect imposed by periodic element and compound when they possess unpaired electrons. Let us find if CaCl2 مغنطيسي أم لا.

Calcium chloride is not paramagnetic rather the magnetic effect of CaCl2 cannot be defined as the compound is found as neutral in nature and with all paired electrons.

Calcium chloride hydrates

There are 5 types of hydrates of Calcium chloride can be obtained that are listed below:

  • Calcium chloride anhydrous (CaCl2)
  • Calcium chloride monohydrate (CaCl2. 1 ح2O)
  • Calcium chloride dihydrate (CaCl2. 2 ح2O)
  • Calcium Chloride tetrahydrate (CaCl2. 4 ح2O)
  • Calcium chloride hexahydrate (CaCl2. 4 ح2O)

Calcium chloride crystal structure

Calcium chloride is found as crystalline solid salt.

Calcium chloride polarity and conductivity

  • Calcium chloride is neither polar nor non-polar as the compound is classified as an ionic compound made off one metal and one non-metal element.
  • Conductivity of calcium chloride is very high with 64300 amounts at a temperature of 180C.

Calcium chloride reaction with acid

Calcium chloride is reactive in presence of different acids. The reactions are listed below:

  • In reaction with dilute sulphuric acid, calcium chloride produces white precipitate of the compound calcium sulphate.
  • In reaction with Hydrochloric acid, the compound dissolves in solution and neutralises Hydrochloric acid. CaCl2 + HCl = HCl2 + كاليفورنيا
  • Calcium chloride cannot undergo in reaction with Nitric acid.

Calcium chloride reaction with base

Calcium chloride can be noticed to react with strong base Sodium hydroxide (NaOH). When the compound is mixed with NaOH, Calcium combines with hydroxide ion and makes calcium hydroxide readily.

CaCl2(aq)+NaOH(aq)→Ca(OH)2(s)+NaCl(aq).

Calcium chloride reaction with oxide

Calcium chloride is not reactive in presence of Oxygen and contact with any oxides. However, it has been obtained that the compound gives out calcium sulphate in reaction with sulphur oxide very slowly.

SO2 + كاكل2 = CaSO2 + Cl.

Calcium chloride reaction with metal

Calcium chloride is found to be highly corrosive in contact with bare metals due to its hygroscopic nature.  All calcium salts also found to impose aggressive nature in the reaction with metals and their alloys. For example, the reaction of CaCl2 with Ferrum or Iron is

Fe + CaCl2 = Ca + FeCl3.

في الختام

Calcium chloride is one of the soft and neutral salts of calcium, which shows its hygroscopic nature as its unique identification. The characteristics of CaCl2 that have been identified in this article are concluding that it is unique in the service of chlorides in chemistry due to the presence of calcium metal in it.
