Question

The least count of burette used normally is x (ml). The value of 10x is:

Answer 1

Hint: Try to recall that burette is a glass tube having a tap at the bottom and is used in labs for the volumetric analysis of an analyte. Now by using this you can easily answer the given question.

Complete step by step solution:
It is known to you that burette looks like a graduated cylinder with a stopcock at the bottom.
They can be used to simply transfer liquids too but they are mostly used in titrations, where you don’t know what volume you are going to need at first.
You can control the flow of the liquid in burette by using the stopcock.
You can completely open it to allow a continuous flow or set it to drip one drop at a time and one drop is 0.05 ml.
The control of flow is what allows burettes to be used in titrations.
You can slowly add a desired amount of liquid until you reach your equivalence point.
Now, coming to the question, it is known to you that least count is the smallest value that can be measured by a measuring instrument and the least count of 50 ml burette is 0.1 ml. So, the value of x is 0.1 ml and the value of 10x is $0.1 \times 10 = 1 ml$.

Note: It should be remembered to you that both burette and pipette are used in redox or acid/base/iodometric titrations.
Also, you should remember that the precision and control of burette is very useful for the purpose of titration.
