Drop Weight Method
Principle-The Drop Weight Method is based on the principle that the weight of a liquid drop formed at the tip of a capillary tube is directly proportional to the surface tension of the liquid. The method involves measuring the weight of definite number of drops of the liquid and weight of same number of drops of distilled water and then calculating the surface tension using the following formula.
(1) Clean the Stalagmometer with chromic
(2) Attach a small piece of rubber tube having a screw pinch cork at the upper end of the Stalagmometer.
(3) Immerse the lower end of the Stalagmometer in distilled water and suck the water 1-2 cm above the upper mark. Adjust the pinch cork so that 10-15 drops fall per minute.
(4) Clamp the Stalagmometer and allow 10 drops of water to fall into the pre-weighed wide mouthed weighing bottle.
(5) Weigh the weighing bottle along with 10 drops of water. Repeat the experiment three to four times.
(6) Rinse the Stalagmometer with the given liquid, dry it. Fill it with the experimental liquid and repeat the above steps.
Precautions-
(1) The Stalagmometer should be perfectly clean to avoid errors.
(2) The temperature of the liquid should be maintained constant.
(3) The drops should form slowly tonensure accurate results convert it in hinglish
