1. When permanganate is added to hydrogen peroxide:
a. Is the conversion of the purple permanganate ion an oxidation or reduction? Explain.
b. what is the gas produced and what is the source of this gas?
c. Is the production of gas in this reaction an oxidation or reduction? Explain
d. What is the oxidizing agent? The reducing agent?
[An oxidizing agent is a reactant that removes
electrons from other reactants during a redox reaction. The
oxidizing agent typically takes these electrons
for itself, thus gaining electrons and being reduced. An
oxidizing agent is thus an electron acceptor.][A
reducing agent is an element or compound that loses an electron to
another chemical species in a redox chemical reaction. Since the
reducing agent is losing electrons, it is said to have been
oxidized. If any chemical is an electron donor, another must be an
electron recipient. ]THANKS HOPE THIS WILL HELP YOU.GOOD LUCK

Over time, hydrogen peroxide, H2O2, degrades into water and oxygen gas. A bottle of hydrogen peroxide is expired and you need to determine the concentration. A titration is performed using the following equation: 3 H2O2(aq) + 2 NaMnO4(aq) → 3 O2(g) + 2 MnO2(aq) + 2 NaOH(aq) + 2 H2O(l) Note that permanganate ion, MnO4-, is purple, while manganese (IV) ion, Mn4+, is colorless. A quantity of 683 mL of 3.44 M NaMnO4 was measured and placed in a beaker. The solution...

The oxidation of iodide ion by hydrogen peroxide in an acidic solution is described by the balanced equation H2O2(aq)+3I−(aq)+2H+(aq)⟶I3−(aq)+2H2O(l)H2O2(aq)+3I−(aq)+2H+(aq)⟶I3−(aq)+2H2O(l) The rate of formation of the red triiodide ion, Δ[I3−]/ΔtΔ[I3−]/Δt, can be determined by measuring the rate of appearance of the color. A sequence of photographs showing the progress of the reaction of hydrogen peroxide (H2O2)(H2O2) and iodide ion (I−)(I−). As time passes (left to right), the red color due to the triiodide ion (I3−)(I3−) increases in intensity. Initial rate data...
