How were burns treated in the First World War?
Picric acid is an organic compound with the formula (O2N)3C6H2OH. The name “picric” comes from the Greek word πικρός (pikros), meaning “bitter”, due to its bitter taste. It is one of the most acidic phenols. Like other strongly nitrated organic compounds, picric acid is an explosive, which is its primary use.
Can picric acid cure shock and septicemia?
to the toxity of the picric acid manifested by skin rashes, irritation, albuminuria, and therefore paraffin had to be substituted, and sepsis not infrequently supervened. Figures and statistics are given to show the improved results and lowered mortality in St. Thomas' Hospital after the intro duction of picric acid.
What is picric acid and tannic acid?
For four or five years the use of picric acid in the treatment of burns has been strongly advocated. Blisters are opened, the dead skin and sloughs are cut away, the wound is thoroughly cleansed, and gauze, soaked in a one percent solution of the acid, is applied to the burnt surface and covered with paraffin paper, and this by a cotton pad, and bandaged lightly.
Is picric acid still used?
Uses. Picric acid is used in the production of explosives, matches, and electric batteries. It is also used in etching copper and manufacturing colored glass, in the leather industry, and in the synthesis of dyes. Picric acid is very unstable and is a flammmable/combustible material.
What is the first aid treatment for acid burns?
Cover the burn with a clean bandage. Wrap it loosely to avoid putting pressure on burned skin. Rinse again if needed. If you feel more burning, rinse the area again for several more minutes.Feb 17, 2022

Why picric acid is stronger than phenol?
Three —NO2 groups in picric acid deactivate the phenolate ion. Due to electron withdrawing nature of —NO2 groups, picric acid becomes stronger acid than phenol.
Does milk neutralize acid burns?
Cool the burn under cold running water for at least 20 minutes. This will help to cool the burn and wash out the chemical. If you don't have access to water, you can use other harmless liquids (ones that you could drink such as milk or cola).
How do doctors treat chemical burns?
You will be given any antidote to counteract the chemical, if appropriate. Antibiotics often are not needed for minor chemical burns. Wounds will be cleaned and bandaged with medicated creams and sterile wraps as needed. Consultation with other medical specialists may be done.Sep 21, 2020
Why is picric acid used in treatment for burns?
Picric acid has antiseptic and astringent properties. For medical use it is incorporated in a surface anesthetic ointment or solution and in burn ointments. Picric acid is a much stronger acid than phenol; it decomposes carbonates and may be titrated with bases.
Which is known as carbolic acid?
Phenol, also known as carbolic acid, is an aromatic organic compound with the molecular formula C₆H₅OH. It is a white crystalline solid that is volatile.
What is catechol used for?
Catechol (1,2-dihydroxybenzene) is used in a variety of applications. It is used as a reagent for photography, dyeing fur, rubber and plastic production and in the pharmaceutical industry (Merck, 1989; Milligan and Häggblom, 1998).Dec 20, 2001
Why picric acid is called an acid?
We know phenol shows acidic nature. 2,4,6-Trinitrophenol is highly acidic in nature as three electron withdrawing groups (Nitro group) are attached to it. These electron withdrawing groups on phenol make it highly acidic. That's why it is known as picric acid.Dec 25, 2014
Which is more acidic phenol or acetic acid?
Answer: Acetic acid is more acidic than Phenol. Acetic acid is a typical carboxylic acid and removal of proton from O-H bond is facilitated by electron withdrawing carbonyl group. But Phenol is stabilised by phenoxide ion via resonance and no such property as acetic acid is not observed yet.Jan 25, 2018
Which is more acidic between phenol and picric acid?
Picric acid is the strongest acid due to the presence of three (NO2) group (-R and -I effect).
