What is the oxidation number for Al2O3?
+3 for Al and -2 for O is the oxidation number for Al2O3.
What is the oxidation number of chlorine in AlCl4?
The oxidation number of chlorine in AlCl4 is -1. Since aluminum has an oxidation number of +3, the overall charge of the AlCl4 ion is -1, meaning each chlorine atom has an oxidation number of -1 to balance the charge.
What are the oxidation numbers of Al OH 4-?
The oxidation number of Al is +3 in the complex ion Al(OH)4-. Each hydroxide ion (OH-) carries a charge of -1, so the total charge of the complex ion is -1. Since there are four hydroxide ions, the aluminum ion must have an oxidation number of +3 to balance the charges.
What is the oxidation number of sulfur in aluminium sulfate?
The oxidation number of sulfur in aluminum sulfate is +6. This is because each oxygen atom has an oxidation number of -2, and there are four oxygen atoms in the sulfate ion (SO4). The overall charge of the sulfate ion is -2, so the oxidation number of sulfur must be +6 to balance the charge.
What is the oxidation number of aluminum in aluminum chloride?
The oxidation number of aluminum in aluminum chloride (AlCl3) is +3. Aluminum typically has an oxidation number of +3 when it forms ionic compounds.
What is the oxidation number for Al2O3?
+3 for Al and -2 for O is the oxidation number for Al2O3.
What is th formula of the compound formed between aluminum ions and phosphate ions?
The formula of the compound formed between aluminum ions and phosphate ions is AlPO₄, which is known as aluminum phosphate. It is composed of one aluminum ion (Al³⁺) and one phosphate ion (PO₄³⁻) to balance the charges and form a neutral compound.

What is the oxidation number of each ion in the compound MgBr2?
In MgBr2, the magnesium ion (Mg) has an oxidation number of +2, while the bromide ion (Br) has an oxidation number of -1.
What is the oxidation number of CO3?
The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
What is the oxidation number of nitrito?
The oxidation number of the nitrite ion (NO2-) is -1. The oxidation number of nitrogen in the nitrite ion is +3, and each oxygen atom has an oxidation number of -2.
How does the oxidation number of a monatomic ion compare to its charge?
The oxidation number of a monatomic ion equals its charge. For example, the oxidation number of a sodium ion (Na+) is +1, which matches its charge of +1.
What is the oxidation number of the molecular ion ammonium NH4 in ammonium chloride NH4Cl?
The oxidation number of nitrogen in the ammonium ion NH4+ is -3, and the oxidation number of hydrogen is +1. In ammonium chloride NH4Cl, the net charge on NH4 is +1 because the chloride ion Cl- has an oxidation number of -1.
How to solve for the oxidation number of charge of a polyatomic ion?
To find the oxidation number or charge of a polyatomic ion, consider the known charges of the individual atoms within the ion. For example, in the sulfate ion (SO4)2-, oxygen typically has an oxidation number of -2, and sulfur would then have an oxidation number to balance the charge of the ion. The sum of the oxidation numbers of all the atoms in the ion should equal the overall charge of the ion.
