What is a phenol solution?
Phenol is an antiseptic and disinfectant. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. Phenol has been used to disinfect skin and to relieve itching.

How do you make phenol solution?
Take 100g phenol bottle to fume hood, open it, and pour in ~ 100 ml 50 mM TrisCl pH 8. Close lid tightly and shake gently. Leave to stand for an hour or two until the phenol liquifies and the phases are separated. Remove the supernatant with a pipette (dispose into the ‘chlorinated solvent waste’ container).
How do you make a 5% phenol solution?
Phenol is moderately soluble in water – about 8 g of phenol will dissolve in 100 mL water. So, take 5 gm phenol crystals and add water to 100 mL.

What is the another name of phenol?
noun Chemistry. Also called carbolic acid, hydroxybenzene, oxybenzene, phenylic acid. a white, crystalline, water-soluble, poisonous mass, C6H5OH, obtained from coal tar, or a hydroxyl derivative of benzene: used chiefly as a disinfectant, as an antiseptic, and in organic synthesis.
What is phenol with example?
Phenols are widely used in household products and as intermediates for industrial synthesis. For example, phenol itself is used (in low concentrations) as a disinfectant in household cleaners and in mouthwash. Phenol may have been the first surgical antiseptic.
Which chemical is used in phenol?
Phenol is also known as carbolic acid. It is an aromatic organic compound with the molecular formula C6H5OH.
How do you make a 1 percent phenol solution?
Preparation of Equilibrated Phenol – Amrita University – YouTube
What is the pH of phenol?
The surface pH of phenol-containing aqueous nanoaerosols is found to be ∼2.2 ± 0.1 units more acidic than that of the bulk interior, as measured at the bulk pH of 12.0.
How do you make an 80% phenol solution?
Combine 555 ml of aqueous phenol (or 500 grams of phenol crystals plus 55 ml of water) with 70 ml of m-cresol. Change the relative amounts according to needs. Phenol is horrendously corrosive and is tremendously hazardous. Use extreme caution when handling this very toxic substance.
Is phenol an alcohol?
Publisher Summary. Phenols have unique properties and are not classified as alcohols. They have higher acidities due to the aromatic ring’s tight coupling with the oxygen and a relatively loose bond between the oxygen and hydrogen.
What phenol is used for?
Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers. It is also used in slimicides (chemicals that kill bacteria and fungi in slimes), as a disinfectant and antiseptic, and in medicinal preparations such as mouthwash and sore throat lozenges.
How will you prepare 0.1 M phenol solution?
Popular Answers (1) weight 0.1 gm of phenol crustal and put it in volumetric flask. add 10 ml ( d.w. desolive it and complete the volume to 100 ml with d.w.
Is phenol acidic or basic?
acidic
Phenols are organic compounds containing a benzene ring bonded to a hydroxyl group. They are also known as carbolic acids. Phenols react with active metals like sodium, and potassium to form phenoxide. This reaction of phenol with metals indicates its acidic nature.
Why phenol is an acid?
Phenol is acidic in nature because it can lose hydrogen ions from its OH bond, as on losing this hydrogen phenoxide ion is formed which is stable. Though it is a weak acid it is in equilibrium with the phenolate anion C6H5O− which is also called phenoxide.
What is another name for phenol?
carbolic acid
noun Chemistry. Also called carbolic acid, hydroxybenzene, oxybenzene, phenylic acid. a white, crystalline, water-soluble, poisonous mass, C6H5OH, obtained from coal tar, or a hydroxyl derivative of benzene: used chiefly as a disinfectant, as an antiseptic, and in organic synthesis.
How do you make a 1% solution?
A one percent solution is defined as 1 gram of solute per 100 milliliters final volume. For example, 1 gram of sodium chloride, brought to a final volume of 100 ml with distilled water, is a 1% NaCl solution.
How do you make a 0.1 molar solution?
To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.
What pH is alcohol?
So, what is the ph of alcohol? The pH value of alcohol is 7.33. Alcohol cannot be defined as acidic or alkaline, rather defined as amphiprotic because the nature of the bond between carbon and hydroxyl group is non-ionic but slightly polar in nature.
Does phenol react with water?
It is fairly insoluble in water. It reacts with sodium hydroxide solution to give a colourless solution (and therefore must be acidic). It does not react with sodium carbonate or hydrogencarbonate solutions (and so must be only very weakly acidic).
What are examples of phenols?
Phenols are common in nature; examples include tyrosine, one of the standard amino acids found in most proteins; epinephrine (adrenaline), a stimulant hormone produced by the adrenal medulla; serotonin, a neurotransmitter in the brain; and urushiol, an irritant secreted by poison ivy to prevent animals from eating its …
What is a 2% solution?
Solvent is in a generally liquid or gaseous state in which the solute dissolves to form a solution. To make a proper 2 percent solution, they should specify a solvent but the general way to make a 2 percent solution is to get 2 grams of solvent and dissolve it in 98-100 ml of water.
What is a 0.1% solution?
0.1% w/v. That means that, for every 100 mL you have 0.1 g. 500 mL. That is the total volume specified. At the quoted concentration then it contains 0.5 g, or 500 mg, of whatever it is that we are talking about.
What is 0.1N solution?
It is indicated using the symbol N, eq/L, or meq/L (= 0.001 N) for units of concentration. For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl. A gram equivalent weight or equivalent is a measure of the reactive capacity of a given chemical species (ion, molecule, etc.).
