Which reaction is not an example of an oxidation reduction reaction?

Answer Expert Verified. Answer is: c. CuSO4 + 2NaOH yields Cu(OH)2 + Na2SO4. Copper atom has oxidation number +2, sulfur atom oxidation number +6, oxygen has oxidation number-2, sodium has oxidation number +1 and hydrogen has +1 on both side of chemical reaction, so elements did not change their oxidation numbers.

What is a non redox reaction?

When a change in oxidation number occurs in a reaction, with both an increase in number and a decrease in number, then the reaction is classified as redox. If this does not occur, then the reaction is non-redox.

Which of the following is not a reduction?

Oxidation state of CinCO2 is +4, which is maximum So it does not undergo oxidation, and hence, it is not a reducing agent.

Is zinc oxidation or reduction?

Sulfur is called the oxidizing agent. The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. The oxidizing agent is a substance that causes oxidation by accepting electrons.

Is gold easily oxidized?

Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Gold has a many unique properties that make it the perfect metal for many industrial uses.

Why gold is not corroded?

– Gold is a noble metal in the periodic table, which is chemically inert and does not get corroded in the natural or industrial environment. This is because the gold does not react with oxygen in the atmosphere. The rest part of the ornament is often made up of silver or other metals like copper, nickel, iron etc.

Can pure gold corrode?

Gold is one of the least reactive elements on the Periodic Table. It doesn’t react with oxygen, so it never rusts or corrodes. Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold.
