Determine if all the starting material is converted to the product.

<h3>What is TLC?</h3>

Because it can provide immediate and important information about a sample's purity and whether or not a reaction is still ongoing, TLC is a common technique in the organic chemistry lab. A TLC plate can be finished in less than 5 minutes when low polarity solvents are used.

<h3>Uses of TLC:-</h3>

TLC is a chromatographic method used to separate mixtures that are not volatile.

Thin-layer chromatography can be used to:-

  • Assess a substance's purity.
  • Identify the compounds present in a particular combination.
  • Track the development of a reaction.

Rank these species by their ability to act as an oxidizing agent. cu+ mg2+ fe2+
natita [175]

Explanation:

The species or elements which gain electrons and reduces itself are known as oxidizing agent or oxidant.

Ability of an element to act as an oxidizing agent depends on its electrode potential.

The electrode potential of Cu^{+} is 0.52 V.

The electrode potential of Fe^2+ is -0.41 V.

The electrode potential of Mg^{2+} is -2.38 V.

Greater is the value of electrode potential, stronger will be the oxidizing agent.

Therefore, rank of these species by their ability to act as an oxidizing agent are as follows.

       Cu^{+} > Fe^2+ > Mg^{2+}
