Answer 2

OBP Process:

The OBP process, also known as the Jones oxidation, is a chemical reaction that involves the oxidation of a primary alcohol to a carboxylic acid using a mixture of potassium dichromate (K2Cr2O7), potassium iodide (KI), and sulfuric acid (H2SO4). The reaction can be represented as follows:

K2Cr2O7 + KI + H2SO4 → Cr2(SO4)3 + K2SO4 + I2 + H2O

Balancing the OBP Process:

To balance the OBP process using an electronic balance, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here is the balanced equation for the OBP process:

6 K2Cr2O7 + 14 KI + 36 H2SO4 → 6 Cr2(SO4)3 + 14 K2SO4 + 7 I2 + 36 H2O

Definition of Oxidation-Reduction Process:

An oxidation-reduction process, also known as a redox process, involves the transfer of electrons between chemical species. In an oxidation process, a species loses electrons, while in a reduction process, a species gains electrons. The species that loses electrons is called the reducing agent or reductant, while the species that gains electrons is called the oxidizing agent or oxidant.

In the context of the OBP process, the primary alcohol is oxidized to a carboxylic acid, while the chromium in the potassium dichromate is reduced from the +6 oxidation state to the +3 oxidation state. The potassium iodide acts as a catalyst in this reaction.

In summary, the OBP process is an oxidation-reduction reaction that involves the oxidation of a primary alcohol to a carboxylic acid using potassium dichromate, potassium iodide, and sulfuric acid. The reaction can be balanced using an electronic balance, and it represents an example of an oxidation-reduction process where electrons are transferred between chemical species.
