What is the meaning of coagulate in English?
1 : to cause to become viscous or thickened into a coherent mass : curdle, clot. 2 : to gather together or form into a mass or group. intransitive verb. : to become coagulated. coagulate.
What is the description of coagulate?
The definition of coagulate means for a liquid to become a soft mass or a clot. An example of coagulate is for blood to clot and congeal into a mass on the edge of a cut in the skin. To cause (a liquid) to become a soft, semisolid mass; curdle; clot.
What is an example of coagulation?
Coagulation is the breakdown of a colloid by changing the pH or charges in the solution. Making yogurt is an example of coagulation wherein particles in the milk colloid fall out of solution as the result of a change in pH, clumping into a large coagulate.
What does coagulate mean in medical terms?
Coagulation, in physiology, the process by which a blood clot is formed. The formation of a clot is often referred to as secondary hemostasis, because it forms the second stage in the process of arresting the loss of blood from a ruptured vessel.
Is coagulation good or bad?
Blood clotting is a natural process; without it, you would be at risk of bleeding to death from a simple cut. Blood clots inside the cardiovascular system are not always so welcome. A clot in the coronary arteries near the heart can cause a heart attack; one in the brain or the arteries serving it, a stroke.
How do you use the word coagulate?
Coagulate in a Sentence 🔉
- Over time the milk will coagulate and become a bottle of disgusting clots.
- The killer did not realize the blood would coagulate on the floor and form a huge blob.
- Soon the candy mixture will coagulate around the apple and form one of my favorite treats.
What happens if the blood does not coagulate?
When the blood doesn’t clot, excessive or prolonged bleeding can occur. It can also lead to spontaneous or sudden bleeding in the muscles, joints, or other parts of the body. The majority of bleeding disorders are inherited, which means they’re passed from a parent to their child.
How long does it take blood to coagulate?
This test is measured in the number of seconds it takes for a blood clot to form: 70 to 120 seconds is the usual amount of time for blood to clot without heparin. 180 to 240 seconds is the usual amount of time for blood to clot with heparin.
What is meant by coagulation value?
“The minimum concentration of electrolyte in millimoles required to cause coagulation of one litre of colloidal solution is called coagulation value”. Additional Information: Coagulation is also known as flocculation or precipitation.
How is coagulation value calculated?
Explanation: Coagulation value is the millimoles of an electrolyte that must be added to 1 L of a colloidal solution for complete coagulation . Therefore , 5 mL of 1 M NaCl = 11000Ă—5=0.005 or 5 m moles .
What is coagulation power?
Coagulating power of an electrolyte is the minimum amount of electrolyte in millimoles that must be added to one litre of a colloidal solution to bring about its coagulation. Coagulation is caused by. (i) Electrophoresis, (ii) Mutual precipitation by mixing oppositely charged sols in proper proportion.
What is coagulation class 12th?
Coagulation or precipitation:-it is a process of aggregating together the colloidal particle so as to change them into large sized particles which ultimately settles as a precipitate. The coagulation is generally brought about by the addition of electrolytes.
What is the principle of dialysis Class 12?
Dialysis is based on the principle that ions can pass through semipermeable membrane whereas colloidal particles cannot pass through it.
How coagulation can be brought about?
Coagulation is the process by which a colloid precipitates out of a solution. The precipitation is brought about by induced aggregation, i.e., by addition oppositely charged sol and persistent dialysis but not by heating and addition of electrolyte.
What is the difference between Lyophilic and Lyophobic?
Lyophobic colloids or lyophobic sols – solvent-hating. When water is a dispersion medium, they are known as hydrophobic….Difference between Lyophilic and Lyophobic Colloids.
| Lyophilic Colloids | Lyophobic Colloids |
|---|---|
| Highly solvated, dispersed particles are covered by a layer of dispersion medium | Dispersed particles are not solvated |
What is Lyophilic and Lyophobic with example?
The colloidal system in which the particles of the dispersed phase have a strong affinity for the dispersion medium are called lyophilic sols. For example, gum, protein, starch. Lyophobic sols are less stable since their stability is due to charge only.
What are the three main differences between Lyophilic and lyophobic colloids?
| Lyophilic colloid | Lyophobic colloid |
|---|---|
| The affinity between disperse phase and dispersion medium is strong. | The affinity between disperse phase and dispersion medium is weak. |
| The viscosity of colloid is higher than that of the dispersion medium. | The viscosity of colloid is same as that of the dispersion medium. |
What are Lyophilic and lyophobic colloids explain with one example?
Examples are: Sol of gum, gelatine, starch etc. are lyophilic sols. On the other hand if dispersed phase tends to repel (i.e., dislike or hatred) dispersion medium, the resultant sol is termed as lyophobic sol. Examples are: Sols of metals, metal hydroxides, metal sulphides etc.
What are Lyophobic colloids give an example?
Lyophobic colloids are the colloidal solutions in which the particles of the dispersed phase have no affinity for the dispersion medium. Colloidal solutions of gold, silver, Fe(OH)3and As2S3 are lyophobic.
What is the example of lyophobic colloids?
-In the lyophilic colloids, there is a strong attraction between the dispersed particles and the dispersion medium. Starch, gum, gelatin, RBC, egg albumin etc are the examples of lyophilic colloids.
