The graduated cylinder is used to measure the volume of KOH and H2SO4 when accurate volume measurement is not required.
In the laboratory certain graduated apparatus are used to measure liquids. These graduated apparatus used to measure liquids include;
- burette
- pipette
- measuring cylinder
- Erlenmeyer flask
Sometimes, we are not really looking for a strictly accurate volume of liquid and we can use a graduated cylinder to measure the volume of liquid in such cases.
However, when we need to have strictly accurate volume measurement, we need a pipet or a buret.

Answer:Hence, the bond length in HCl is 125 pm.
Explanation:
Bond length : It is an average distance between the nuclei of two bonded atoms in a molecule.
Also given that bond length is the distance between the centers of two bonded atoms. on the potential energy curve, the bond length is the inter-nuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Beyond this if atoms come closer to each other then their will be repulsion between them.
So, the bond length between the Hydrogen and Chlorine atom in HCl molecule is :

Hence, the bond length in HCl is 125 pm.
