Remove the drop suspended from a pipet tip by … b. The finger used to control the delivery of liquid form a pipet is the … c What should be done with the last bit of liquid remaining in the pipet after delivery? d. Most pipets are calibrated as TD 20 degree C. Define TD: what is its meaning regarding the volume of liquid a pipet delivers? Experimental Procedure, Part C.1. The density of diamond is 3.51 g/cm^3, and the density of platinum is 21.43 g/cm^3. If equal masses of diamond and platinum are transferred to equal volumes of water in separate graduated cylinders, which graduated cylinder would have the greatest volume change? Explain or show with a sample calculation. Experimental Procedure, Part C.3. The MB of a beaker is 5.333 g. After 5.00 mL of a concentrated hydrochloric acid solution is pipetted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229 g. From the data, what is the measured density of the hydrochloric acid solution?
6 a by touching it to the base or wall of the beaker
b index finger is used
cvolume of the glass pipet that is remained is excluded with the factor of liquid remainig it wont affect the volume used,you can leave that liquid
d TD means to deliver amount of liquid remaining should not be blown out.
