What is back suction and why does it have to be avoided
Asked by Varun Vashi | 06 Aug, 2013, 06:54: PM
Expert Answer
HCl is soluble in water so it is absorbed in water more quickly . so in the preparation of HCl the pressure in the delivery tube and flask is reduced and atmospheric pressure from outside forces the water back upto the delivery tube . this effect is back suction
Avoid suctioning too frequently as this could lead to more buildup.
