Options

  1. AWhat does the intense blue color formed by the addition of starch indicate in the Iodometry?
  2. BWhat does the intense blue color formed by the addition of starch indicate in the Iodometry?
  3. CWhat does the intense blue color formed by the addition of starch indicate in the Iodometry?
  4. DWhat does the intense blue color formed by the addition of starch indicate in the Iodometry?

Correct answer

C. What does the intense blue color formed by the addition of starch indicate in the Iodometry?

Step-by-step solution

At time t=0,t = 0, voltage across the first zener diode is increases linearly till it reaches it's breakdown voltage of 4V4V, after that voltage increases linearly till it reaches the breakdown voltage of second zener diode,

As soon as voltage across the zener diode reaches the breakdown voltage of 6V6V of second zener diode, volatge becomes constant and doesn't change with time.
