Describe the scale used to measure the basicity of a substance. Demonstrate how you could differentiate a weak base from a strong one

Basicity is measured on a scale called the pH scale. On this scale, a pH value of 7 is neutral, and a pH value of more than 7 to 14 shows increasing basicity.

pH value of 7 is weak base and value of 14 means strong base.

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
