Converting metal oxides to molten chlorides for electrolytic reduction involves several steps: *Chlorination processes:* 1. *Hydrochloric acid (HCl) reaction*: React metal oxide with HCl gas or solution to form metal chloride. Example: Al2O3 + 6HCl → 2AlCl3 + 3H2O 2. *Carbochlorination*: React metal oxide with chlorine (Cl2) and carbon (C) at high temperatures. Example: Al2O3 + 3C + 3Cl2 → 2AlCl3 + 3CO 3. *Chlorine gas reaction*: Directly react metal oxide with chlorine gas. Example: TiO2 + 2Cl2 → TiCl4 + O2 *Other methods:* 1. *Metal chloride synthesis*: React metal oxide with other chlorides (e.g., NaCl, KCl) at high temperatures. Example: Al2O3 + 2NaCl → 2AlCl3 + Na2O 2. *Hydrochloric acid leaching*: Dissolve metal oxide in HCl solution, then evaporate to obtain metal chloride. *Molten salt preparation:* After obtaining metal chloride, mix it with other salts (e.g., NaCl, KCl, CaCl2) to create a molten salt bath for electrolysis. This mixture reduces the melting point and improves conductivity. *Examples of electrolytic reduction:* 1. Aluminum (Al) from Al2O3 via AlCl3 2. Titanium (Ti) from TiO2 via TiCl4 3. Magnesium (Mg) from MgO via MgCl2 Keep in mind: - Reaction conditions (temperature, pressure, and atmosphere) vary depending on the metal oxide and desired chloride. - Purification steps may be necessary to obtain high-purity metal chlorides.
Ma'am as u have said that we need to take chlorides of highly reactive metals but from where do we obtain that respective chlorides of metal as they are present in oxides??

In iron electrolysis refining, iron(II) sulfate (FeSO4) is commonly used as the electrolyte. However, iron doesn't deposit at the anode because: *Anode reaction:* 2FeSO4 → 2Fe2+ + 2SO42- + 2e- (oxidation) At the anode, iron(II) ions (Fe2+) are oxidized to iron(III) ions (Fe3+), releasing electrons. This process prevents iron deposition at the anode. *Reasons iron doesn't deposit at the anode:* 1. *Oxidation state*: Iron(II) ions are oxidized to iron(III) ions, making deposition impossible. 2. *Electron release*: Electrons are released during oxidation, which are used to sustain the electrolysis process. 3. *Solubility*: Iron(III) ions remain soluble in the electrolyte, preventing precipitation. *Cathode reaction:* Fe2+ + 2e- → Fe (reduction) At the cathode, iron(II) ions are reduced to pure iron, depositing on the cathode surface. *Why iron deposits at the cathode:* 1. *Reduction state*: Iron(II) ions are reduced to pure iron. 2. *Electron gain*: Electrons are gained during reduction, allowing iron deposition. 3. *Insolubility*: Pure iron is insoluble in the electrolyte, facilitating deposition. In summary, iron doesn't deposit at the anode due to oxidation, electron release, and solubility, whereas it deposits at the cathode due to reduction, electron gain, and insolubility.

Mam magnesiumoxide is highly reactive oxide but when use the aluminum as a reducing agent so aluminum displace the magnesium Bec aluminum is highly reactive metal so here aluminum reduced the high reactive metal oxide ab Kya hoga mam

Good question bro
I think from Ocean
Seawater contains insoluble salts like NaCl and MgCl2
Highly reactive metal ka reaction hydrochloric acid ke saath krwayege toh metal chloride obtain hoga
Mam but aapne kha tha ki highly reactive metals ki oxides, carbonates, and sulphides hoti h

Mam why in electrolysis refining the sulphate being negative ion do not deposited at anode
In iron electrolysis refining, iron(II) sulfate (FeSO4) is commonly used as the electrolyte. However, iron doesn't deposit at the anode because:
*Anode reaction:*
2FeSO4 → 2Fe2+ + 2SO42- + 2e- (oxidation)
At the anode, iron(II) ions (Fe2+) are oxidized to iron(III) ions (Fe3+), releasing electrons. This process prevents iron deposition at the anode.
*Reasons iron doesn't deposit at the anode:*
1. *Oxidation state*: Iron(II) ions are oxidized to iron(III) ions, making deposition impossible.
2. *Electron release*: Electrons are released during oxidation, which are used to sustain the electrolysis process.
3. *Solubility*: Iron(III) ions remain soluble in the electrolyte, preventing precipitation.
*Cathode reaction:*
Fe2+ + 2e- → Fe (reduction)
At the cathode, iron(II) ions are reduced to pure iron, depositing on the cathode surface.
*Why iron deposits at the cathode:*
1. *Reduction state*: Iron(II) ions are reduced to pure iron.
2. *Electron gain*: Electrons are gained during reduction, allowing iron deposition.
3. *Insolubility*: Pure iron is insoluble in the electrolyte, facilitating deposition.
In summary, iron doesn't deposit at the anode due to oxidation, electron release, and solubility, whereas it deposits at the cathode due to reduction, electron gain, and insolubility.
Nice explanation❤

What is the meaning of stable in chemistry why the highly reactive metals are more stable?
Because they complete the octet rule....There valence shell is complete with 8 electrons

Thank you for your question! When a substance undergoes combustion, it reacts with oxygen to release heat.
Why chlorine releases its one electron on aniom

Yes u r right but both are true we can either carry out process in absence of air as well as in presence of limited amount of air....both are correct
It's says "in limited air" which also means absence of air, not completely without air, but with small amout of air or oxygen. Hope this help👍
