In aluminum chloride (AlCl3), the valency of chlorine (Cl) is -1. Each chlorine atom gains one electron to achieve a stable electron configuration, resulting in a negative charge. Since there are three chlorine atoms in AlCl3, they collectively balance the +3 charge of aluminum (Al), which has a valency of +3. Thus, the overall compound is electrically neutral.
3 mol Cl- ions per mol AlCl3 , so 3 * 0.5 = 1.5 mol/L Cl-
This is Cl, chlorine, with multiple valency values: -1, +1, +3, +5, +7

The valency of lead (Pb) in PbCl2 is +2, as it forms two chloride ions (Cl-) with a -1 charge each, resulting in a neutral compound. In PbCl4, the valency of lead is +4, as it forms four chloride ions. Therefore, PbCl2 has a lead valency of +2, while PbCl4 has a lead valency of +4.
The valency of AlCl3 is 3. This is because aluminium (Al) has a valency of +3 and each chlorine atom (Cl) has a valency of -1, so it takes 3 chlorine atoms to balance the charge of one aluminium atom.
The correct formula is AlCl3
AlCl3 is the correct formula as the valency of aluminium and chlorine are 3 and 1 respectively.
Symbol: Cl-Valency: -1.
1 mol of AlCl3 has mass 133.5 g and has 3 mol Cl- atoms so 400.5 g AlCl3 means 3 mol AlCl3 which means 9 mol Cl- atoms. So Ans = 9 X 6.022 X 1023 = 5.4198 X 1024 Cl- atoms
3 mol Cl- ions per mol AlCl3 , so 3 * 0.5 = 1.5 mol/L Cl-

1 mole of AlCl3 will dissociate into 4 moles of ions in aqueous solution: 1 mole of Al+3 ions and 3 moles of Cl- ions.
This is Cl, chlorine, with multiple valency values: -1, +1, +3, +5, +7
In fact an electron has no valency, though it is equal to a -1 (minus one) charged anion like Cl-, having a valency of -1
The electronegativity difference between Al and Cl in Aluminum Chloride (AlCl3) is around 1.5. Aluminum is less electronegative than chlorine, so there is a moderate polarity in the Al-Cl bond.
Aluminium chloride (AlCl3) contain Al and Cl.
