What happens when ferric chloride is dissolved in water?
When ferric chloride is dissolved in water the solution becomes strongly acidic as a result of hydrolysis. The chemical reactions, in words and formulae are: Schematic representation of the chemical interactions occurring during etching copper in ferric chloridesolution.
Why ferric chloride is acidic in nature?
Neutral FeCl3 reacts with phenol to give a characteristic coloured solution. Acidic or basic FeCl do not give this reaction with phenol because if the ferric chloride is acidic or basic in nature a commom acid-base neutralization will take place and a precipitate of the salt will be formed.
How does ferric chloride clean water?
As a flocculant, chemicals that help small particles in water clump together so they can be removed, Ferric Chloride is dissolved in solution, where it forms an aqueous brown tinted solution. The solution is used to clear water of particles.
What happens when you add ferric chloride to water?
Ferric Chloride or Iron (III) Chloride (FeCl3) is used as a flocculant in sewage treatment and drinking water production. When small quantities of ferric chloride are added to the raw water, iron(III) hydroxide precipitates and adsorbs finely divided solids and colloids.
Why is ferric chloride used as a coagulant?
Ferric chloride is the coagulant of choice for many industrial and sanitary wastewater treatment applications, due to its high efficiency, effectiveness in clarification, and utility as a sludge dewatering agent. The chemical leaves slight residual color, and offers very good turbidity removal.
What is the ferric chloride test used for?
Ferric Chloride Test This test is conducted to determine the presence or absence of phenol in a given sample. Compounds such as enols, hydroxamic acids, sulfinic acids, and oximes give positive results. The quantity of phenol in the sample can be measured by the Folin-Ciocalteau assay.
What does ferric chloride react with?
Ferric chloride solutions in water are strong acidic but in their reaction with copper no significant fumes or gases are produced. Simply, except in the presence of free oxygen, copper will not react to any significant extent with hydrochloric acid which is the acid produced with ferric chloride solutions.

What is coagulant in water treatment?
A coagulant is a chemical that is used to remove suspended solids from drinking water. They are made up of positively charged molecules, which help to provide effective neutralization of water.
Does ferric chloride lower pH?
Iron-based coagulants, such as ferric chloride, ferric sulphate and PFS®, are not that popular in Australia and tend be more expensive than alum on an equivalent dose basis. They also consume more alkalinity than alum, and hence tend to depress pH of the dosed water much more.
Which coagulant is used for sewage treatment?
Ferric chlorideFerric chloride is widely used for sewage treatment and Alum is widely used for water treatment.
Is ferric chloride soluble in water?

Is ferric chloride an electrolyte?
The complete dissociation into ionic products means that iron (III) chloride is classified as a strong electrolyte.
Is FeCl3 soluble or insoluble in water?

What is the best replacement for ferric chloride?
Both large and small plants will see cost savings; the more ATS 806 is used to replace ferric chloride, the larger the savings. It should be noted that both ATS 835 and 806 are potentially excellent replacements for alum or ferric chloride—it’s all dependent on the chemistry.
What is a coagulant in water treatment?
As every water treater knows, coagulants are used in the first step of water treatment; they destabilize the water so micro flocks can begin to form. This is followed up by a polymer, which turns it into a larger flock by creating a bigger charge. Alum and ferric chloride are two widely-used “commodity chemical” coagulants ...
Is ferric chloride a competitor for alum?
Some water treaters simply aren’t aware of alternative products. The companies that supply alum and ferric chloride aren’t advertising competing products, and the companies that do sell alternative products struggle to get the word out.
Can alum be used to treat dirty water?
To treat excessively dirty water, simply increasing the alum isn’t going to do anything. For example, to treat muddy water like that from the Mississippi, even 250 parts of alum isn’t going to cut it. Alum just doesn’t work in very dirty water. It produces a lot of sludge.
Is ATS 806 better than ferric chloride?
This product is not only a successful replacement but also offers a much better quality of water for the same dollars spent. ATS 806 removes much more total organic carbon than either alum or ferric chloride. And while it may be a bit more expensive than the ferric, the amount needed is roughly only 25% of the amount of ferric required, ...
What are the applications of ferric chloride?

What is ferric chloride?
Ferric chloride is a common compound of iron and chlorine in which iron possesses +3 oxidation state. It’s IUPAC name is Iron (III) chloride or Iron trichloride. Apart from ferric chloride it has several common names such as molysite and flores martis. It possesses various colours such as in its anhydrous form it appears black-green or purple ...
Is ferric chloride filtered before use?
It is filtered before use. The organic substance or sample is dissolved in water, methanol or ethanol in a test tube. Now the above taken neutralized ferric chloride solution is added in the test containing the solution of the sample.
What is the best way to store ferric chloride?
For safe storage, we recommend a high-density crosslinked polyethylene tank. Ferric chloride is also a high fuming chemical. These fumes can potentially defoliate surrounding trees and plants. When storing Ferric Chloride in a chemical storage tank, a fume-tight manway lid cover prevents fumes from escaping the tank.
What is flocculant in water?
A flocculant is a substance that promotes the clumping of particles so that they may be removed from water. Flocculants are essential in proper water treatment. One particularly popular flocculant is Ferric Chloride.
Is ferric chloride a pure iron?
As one of the purest and most concentrated forms of iron commercially available for water treatment, Ferric Chloride has a unique distinction. In order to produce Ferric Chloride, Ferrous Chloride must be used. It is the oxidation of Ferrous Chloride with Chlorine that creates this new compound.
