Difference between calcium chloride and fused calcium chloride?
Calcium chloride is a salt that is typically in the form of a solid or solution. Fused calcium chloride refers to the solid form of calcium chloride that has been heated to its melting point and then cooled to solidify. Fused calcium chloride has a higher purity and is often used in more specialized applications compared to regular calcium chloride.
Why alkali metals are prepared by electrolysis of their fused chlorides?
Alkali metals are prepared by the electrolysis of their fused chlorides because this method effectively separates the metal ions from their chloride counterparts. In the molten state, the chlorides allow for the conduction of electricity, enabling the reduction of metal cations at the cathode and the oxidation of chloride anions at the anode. This process is necessary since alkali metals are highly reactive and cannot be easily obtained through traditional chemical reduction methods. Additionally, the electrolysis process provides a direct and efficient means to isolate these metals in their pure form.
What method would you use to extract aluminum from its ore?
Aluminum is found in an ore called Bauxite. Bauxite is made up of two compounds: Iron(III) Oxide Fe2O3 and Aluminum Oxide Al2O3.Aluminum Oxide is amphoteric (reacts with acids and bases) while Iron(III) Oxide is basic (reacts only with basis). So here are the steps:Bauxite is crushed to increase surface area.Sodium Hydroxide (NaOH) is made to react with the crushed Bauxite.Al2O3 dissolves forming Sodium AluminateFe2O3 is basic and is insoluble in the alkali.Filter the mixture to remove the insoluble Fe2O3 to get pure Al2O3 (Alumina)Electrolysis to obtain Aluminum, balanced equation:2Al2O3 ---> 4Al + 3O2Al3+ + 2e- --> AlO2- --> O + 2e-
Why organic compound fused with sodium metal?
It is for the detection of some specific elements in organic compound, in organic compounds elements are bonded through covalent bonds and are not free to move, when organic compounds are fused with sodium metal the elements form ionic compounds with sodium and become free ions in aqueous solution therefore easily may be detected with the help of suitable reagents.
Does strontium chloride conduct electricity?
Yes, strontium chloride is an ionic compound and can conduct electricity when dissolved in water or when molten. In its solid state, strontium chloride does not conduct electricity as the ions are not free to move.
What happens when electric current is passed through fused sodium chloride?
During this electrolysis are obtained chlorine and sodium.
What is the difference between fused sodium chloride and brine?
1. Brine is water solution of sodium chloride. 2. "Fused" NaCl is melted sodium chloride.
Which metal is usually produced by the electrolysis of its fused salt iron or copper or sodium or lead?
This metal is sodium.
Name the two ions found in sodium chloride?
The two ions found in sodium chloride are sodium ion and chloride ion. Actually sodium chloride crystals are made up of these two ions which are arranged in a cubical crystal structure with each ion surrounded by 6 ions of the other type1 . The sodium ion is positively charged( called cation) and chloride ion is negatively charged( called anion) and due to electrostatic forces of attraction they are held together.[ Na+Cl- ] ---> Na++ Cl-(in solid) (in solution or fused state)In solid state ions are held together but in fused state or in aqueous solution ions get separated and become mobile. Electrolysis of such a solution can give information about composition of sodium chloride.1. The coordination number of sodium chloride is 6
When was sodium identified as an element?
Sodium (aka, Natrium) Na, at. wt. 22.997, at. no. 11, valence 1 was first isolate by Sir Humphrey Davy in 1807 by electrolysis of fused sodium hydroxide (NaOH)

Why is sodium ions reduced to na while calcium does not in the electrolysis of fused nacl infact both ions are present in it. cacl2 to lower the melting point of na?
Sodium ions are reduced to form sodium metal because sodium has a lower reduction potential than calcium. This means it requires less energy to convert sodium ions into sodium metal compared to calcium ions into calcium metal. The presence of CaCl2 in the fused NaCl helps lower the melting point of NaCl, making the electrolysis process more efficient.
Which element is normally obtained by the electrolysis of its fused salts?
Aluminum is normally obtained by the electrolysis of its fused salts, such as aluminum oxide (Al2O3) dissolved in molten cryolite.

Why is NaCl a strong electrolyte?
Sodium chloride is a strong electrolyte in solution or melted because is dissociaced in ions Na+ and Cl-.
Why fused calcium chloride is used in the preparation of feric chloride?
Fused calcium chloride is used in the preparation of ferric chloride as a dehydrating agent. It helps to remove any water present in the reactants or products, ensuring the reaction proceeds efficiently. Additionally, fused calcium chloride can help to purify the ferric chloride product by absorbing impurities and moisture.
