Question

Dakins’ solution is prepared using bleach and sterile water for irrigation. If the final concentration is 0.25% how much hypochlorite should you add to a 2000ml bottle?

Answer 1

Dakins' solution is a type of hypochlorite solution made of bleach that is diluted and treated for irrigation. it is a strong antiseptic agent that can kill many forms of  bacteria and viruses.

The final concentration of the Dakins' solution should be 0.50%

here, the final concentration=0.25%

Total amount of solution=2000 ml

the amount of hypochlorite should be added=?

1:100 is the normal dilution formula

hence each ml contains only half of the strength in this solution, ie, 0.50:100.

so the sodium hypochlorate initially added dose should be again added to double the concentration.
