oxidation number of nahso4

A LEVEL

Increase in oxidation number is oxidation Decrease in oxidation number is reduction We can apply a series of rules to assign an oxidation state to each atom in a substance Examples The oxidation number of S in H2SO4 H2 S O4 2 x +1 ? 4 x -2 = 0 +2 ? -8 = 0 +2 +6 -8 = 0 s = +6 The oxidation number of S in S2O82-S2 O4 ? 8 x -2 = -2 ? -16

Gold Parting using Nitric Acid

A B and C were then boiled with 5cc of strong acid washed dried and weighed The weights were: A—13 157 B—10 050 C— 9 990 It is therefore clear that 2 of silver and 1 of gold are sufficient for parting and that 1 5 to one is ample if the resultant gold is subsequently treated by sulphuric acid or bisulphate of sodium

Nitric acid

Nitric acid is subject to thermal or light decomposition and for this reason it was often stored in brown glass bottles: 4 HNO 3 → 2 H 2 O + 4 NO 2 + 2 O 2 This reaction may give rise to some non-negligible variations in the vapor pressure above the liquid because the nitrogen oxides produced dissolve partly or completely in the acid

Chemistry MCQ thread

01 06 2011the equation is NaCl + H2SO4 ----- NaHSO4 + HCl if u look to each oxidation number of each element u will find out that there is no change in any of the oxidation numbers so thats why H2SO4 is not acting as an oxidising agent but it acts as an acid as it is an acid/base reaction which forms a salt
