Chapter 6: Problem 5

Bleeding is stopped by applying \(\mathrm{FeCl}_{3}\) because: (a) blood starts flowing in opposite direction (b) \(\mathrm{FeCl}_{3}\) seals the blood vessels (c) blood gets coagulated (d) blood vessel is sealed

Short Answer

Expert verified
Option (c), blood gets coagulated, is the correct answer. \(\mathrm{FeCl}_{3}\) is found to cause coagulation, or clottings, in the blood which helps staunch bleeding.

Step by step solution

01

Identify False Options

Examine the given options and rule out those which are logically incorrect. Here, option (a) is not viable because \(\mathrm{FeCl}_{3}\) would not cause the blood to flow in the opposite direction. Option (b) is also incorrect, \(\mathrm{FeCl}_{3}\) does not seal blood vessels.
02

Evaluate Remaining Options

Evaluate the remaining options that could possibly be correct. Here, we have two left - option (c): the blood gets coagulated and option (d): the blood vessel is sealed. \(\mathrm{FeCl}_{3}\) is known to be a coagulative agent, which points to option (c) as being the correct one. It is unlikely that \(\mathrm{FeCl}_{3}\) seals the blood vessel, as it works on blood coagulation rather than manipulating the blood vessels themselves.
03

Choose The Correct Option

The correct answer is then the one that is logically and scientifically correct according to the properties and use of \(\mathrm{FeCl}_{3}\). Therefore, the correct answer is option (c): the blood gets coagulated.
