What is the oxidation number of CaO2?
Answer: The Compound is CaO. The Oxidation state of Calcium Ca = 2 and for Oxygen O = -2. Answer : Hence the Oxidation state of Calcium is +2 and Oxygen is-2 and the compound is said to be stable.
What is the charge of CaO2?
In calcium peroxide, Ca has a +2 charge. Therefore, the charge of the cation in calcium peroxide is +2.
What is the oxidation number of Cl in ClO4?
The oxidation number of of oxygen is -2 in ClO4- ion and that of chlorine is +7.
What is the oxidation number of chlorine?
Cl has a -1 oxidation number, except when bonded to a F or an O. Br has a -1 oxidation number, except when bonded to a F, a Cl, or an O.
What is the oxidation number of H in nabh4?
As the oxidation state of Na is +1 and Hydrogen is -1 because here hydrogen exist as hydride. Hence the oxidation state of boron is +3. HOPE IT HELPS.
What is the oxidation number of nahso4?
The oxidation state of sulfur in sodium hydrogen sulfate is +6 .
Why does oxygen have an oxidation number of 2?
Oxygen has an oxidation number of +2 because the single oxygen atom has “gained” a total of two electrons, one from each hydrogen. In hydrogen peroxide, each hydrogen still has an oxidation number of +1 because each hydrogen “gives up” a single electron to oxygen.
Is the oxidation number of oxygen always 2?
The oxidation state of the oxygen is -2, and the sum of the oxidation states is equal to the charge on the ion….Working out oxidation states.
|element||usual oxidation state||exceptions|
|Group 2 metals||always +2|
|Oxygen||usually -2||except in peroxides and F2O (see below)|
Can chlorine have an oxidation number of +7?
The oxidation number of chlorine can be -1, 0, +1, +3, +4, +5, or +7, depending on the substance containing the chlorine. The most common oxidation numbers are -1 (as in HCl and NaCl ) and 0 (as in Cl2 ).
What is the oxidation number of chlorine in kclo3?
That means that the charge on chlorine in potassium chlorate is +5 .
