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 ferric chloride is added 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.
What does ferric do water treatment?
Ferric Chloride offers versatility in the water treatment industry, by working as a flocculant and coagulant, as well as a reactant. It promotes faster sedimentation in general and specifically, better sedimentation in cold water, making it an ideal choice for the industry.
How ferric chloride works as a coagulant?
Ferric chloride (FeCl3) is the most common iron salt used to achieve coagulation. Its reactions in the coagulation process are similar to those of alum, but its relative solubility and pH range differ significantly from those of alum. Both alum and ferric chloride can be used to generate inorganic polymeric coagulants.
How does Fe3+ react with water?
When iron ions react with water, some of the iron ions will combine with water molecules, like this: Fe3+(aq) + 3H2O(l) --> Fe(OH)3(s) + 3H+(aq).
Does ferric chloride dissolve in 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.
Why is ferric sulphate used in water treatment?
Ferric-based coagulant acid strength and associated optimized flocculation pH ranges can produce purified water with less buffering capacity and require greater chemical addition for stabilization and corrosion control. High alkalinity consumption. Sulfate and/or chloride in finished water increases corrosion.
Why does ferric chloride stop bleeding?
Ferric chloride is used to stop bleeding in cuts because Fe3+ coagulates blood which is negatively charged sol. As we know blood is a colloidal sol. On rubbing the injured part with Fe3+ then coagulation of blood takes place. Hence, main reason is coagulation, which stops bleeding.
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.
What is flocculation in water treatment?
Flocculation is a water treatment process where solids form larger clusters, or flocs, to be removed from water. This process can happen spontaneously, or with the help of chemical agents. It is a common method of stormwater treatment, wastewater treatment, and in the purification of drinking water.
What two chemicals are commonly used as water coagulants?
Aluminum sulfate (alum) is the most common coagulant used for water purification. Other chemicals, such as ferric sulfate or sodium aluminate, may also be used. Coagulation is usually accomplished in two stages: rapid mixing and slow mixing.
What is ferric chloride?
In the laboratory, ferric chloride is commonly used as a Lewis acid for catalyzing reactions, such as Friedel-Crafts reaction of aromatics and chlorination of aromatic compounds. Ferric chloride, also called iron chloride, is a chemical compound with a chemical formula of FeCl3. It has a relatively low melting point, ...
What percentage of ferric chloride is sold in municipal bids?
This is one of the few water treatment chemicals that can sequester odors. In the U.S., more than 80 percent of all ferric chloride is sold in municipal bids, with 65 percent sold for municipal wastewater applications, and 18 percent for potable water treatment applications. ADVERTISEMENT.

Is ferric chloride a metal?
It is a covalent compound although iron is a metal and chlorine is a non-metal. In ferric chloride, iron gets partial positive charge and chlorine atoms get partial negative charge as chlorine is more electronegative than iron so it pulls a shared electron pair towards itself.
