to how many decimal places should the volume of a liquid in a burette be recorded
Burette The amount of solution added in or drained out needed to be read correctly by observing at eye level straight to the bottom of "Meniscus" for most solutions. Before reading the data, the bubbles must all been removed from the Burette otherwise the data will be inaccurately measured.[10] Also, reading the data at the eye level means looking straight at the bottom of the meniscus. The initial and final volumes collected will be calculated for the difference in volume which equal to the total volume of solution drained out of the Burette. The difference in volume can be calculated by taking the difference of final volume and initial volume[11] Using the Burette with a colorless solution is sometimes difficult to observe the bottom of the meniscus so Black Strip Technique[12] can help to accurately observe and measure the number on the scale. Moreover, the number should be reported in two decimal places, which can be done more easily by using the Black strip Technique. The black strip can be written with pen on the normal white paper or it can be printed it out. However, it is necessary to use white color paper as the background, in order to make the scale readable.[12]
