Answer:

The serial dilution can be done by half- logarithmic dilution method.

Explanation:

  • This is also called the Ten-fold dilution method.
  • The process involves the following steps, and the volumes represented are arbitrary.
  1. From the concentrated solution of the disinfectant take 1 ml of disinfectant in a falcon tube. 9 ml of water is added to that. Here we get a solution which is  \frac{1}{10} diluted.
  2. Take 1 ml of the above \frac{1}{10} diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is  \frac{1}{20} diluted.
  3. Take 1 ml of the above \frac{1}{20} diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is  \frac{1}{40} diluted.
  4. Take 1 ml of the above \frac{1}{40} diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is  \frac{1}{80} diluted.
