What is the oxidation number for KClO3?
So, the sum of oxidation states of each element is zero. Hence, the oxidation state of chlorine in KClO3 is +5 .
What is the oxidation number of chlorine atom in sodium chlorate NaClO4?
The oxidation number of chlorine in the compound NaClO4 N a C l O 4 is a +7.
What is oxidation number for sodium?
+1
Sodium’s oxidation state is +1 since it is a Group 1 metal. The oxidation state for F is -1 in a compound. The oxidation state for H is +1 in a compound. The oxidation state for O is -2 in a compound.
What is the oxidation number of Cr in cr2o72?
+ 6
The sum of the oxidation numbers in Cr2O72-, a polyatomic ion, is -2, the charge of the ion. There are seven oxygen atoms, so the total charge is − 2⋅7 = − 14. So, a chromium atom here has an oxidation number of + 6.
Is the oxidation number of sodium always 1?
The oxidation number of Na has gone from 0 to +1. The oxidation number of Cl has gone from 0 to -1. Yes, this is a red-ox reaction. One electron was transferred from a Na (if you say “sodium” you do not need an “an”…a sodium atom) atom to a Cl atom.

What is the oxidation number of chlorine in naclo_2?
+3 NaClO_2 has the proper name sodium chlorate(III). The (III) is the oxidation number of chlorine in the chlorate ion here. To work thus out you need to know that sodium in compounds always has an oxidation number of +1 ( which you’d expect as it is in Group 1), and oxygen has an oxidation number of -2 in its compounds (except for peroxides).
What is the chemical formula for sodium chlorate?
Sodium chlorate is an inorganic compound with the chemical formula NaClO3. It is a white crystalline powder that is readily soluble in water. It is hygroscopic. It decomposes above 300 °C to release oxygen and leave sodium chloride. Several hundred million tons are produced annually, mainly for applications in bleaching paper.
What is the purpose of sodium chlorate?
Sodium chlorate is an inorganic sodium salt that has chlorate as the counter-ion. An oxidising agent, it is used for bleaching paper and as a herbicide. It is also used in the manufacture of dyes, explosives and matches. It has a role as a herbicide. It is an inorganic sodium salt and a chlorate salt.
What is the oxidation number of oxygen in sodium in Group 1?
1 Answer. To work thus out you need to know that sodium in compounds always has an oxidation number of +1 ( which you’d expect as it is in Group 1), and oxygen has an oxidation number of -2 in its compounds (except for peroxides). You then use the rule that the sum of the oxidation numbers in a compound must add to zero,…
