the oxidation number for potassium is 1.
Potassium typically has an oxidation number of +1. This is because it readily gives away its one valence electron to form a stable ion.
The minimum oxidation number for nitrogen is -3.
Potassium's minimum oxidation number is zero.Its maximum is plus one.
4, 3, 2, 1 (weakly basic oxide) Maximum Oxidation number: 4 Minimum Oxidation number: 0
group 1
The oxidation number of antimony in Sb2O5 is +5. Each oxygen atom has an oxidation number of -2, so the total contribution of oxygen is -10. Since the compound is neutral, the sum of oxidation numbers must be zero, leading to +5 for antimony.
Arsenic is in group 15, it can lose 5 valence electrons or gain 3 valence electrons to achieve the octet. Its minimum oxidation state we can predict as being -3, and its maximum as +5
Minimum oxidation number: -1 Maximum oxidation number: 1 Min. common oxidation no.: 0 Max. common oxidation no.: 1 I got this of a really cool website that has alot of infromation and useful facts about each element and trust me you'll use it a lot in chemistry. www.chemicool.com
I believe K2CO3.
For HClO oxidation No. is '0' . It is a neutrally charged molecule. However, The chlorine atom is in oxidation state (+1). How so???? you may ask . Using oxygen as that standard at '-2' , and hydrogen at '+1' We create a little sum +1 + Cl -2 = 0 ( overall charge on the molecule). Collecting terms Cl - 1 = 0 Cl = + 1 as required. NB When dissolved in water chlorine disproportionates. That is it simultaneously oxidises and reduces., Cl2(aq) = Cl^(+)(aq) + Cl^(-)(aq) It reacts with water molecules to form ;- Cl2 + H2O = HClO + HCl The supply of drinking water from public sources has chlorine bubbled through to act as a bacteriocide (kill the bugs). So tap/faucet water is a very weak solution of hydrochloric acid(HCl) and Hydrogen chlorate(bleach)(HClO). It won't harm you, because the solution is so weak, but just enough to kill the bugs.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
