    1. Density measurement: The density of a liquid can be measured using a hydrometer or a digital density meter. This can help to confirm the identity of the liquid, as different inorganic acids have different densities.
    2. pH measurement: The pH of a liquid can be measured using a pH meter or pH paper. Inorganic acids typically have a low pH, so measuring the pH of the liquid can help to confirm that it is an inorganic acid.
    3. Conductivity measurement: The conductivity of a liquid can be measured using a conductivity meter. Inorganic acids are generally good conductors of electricity, so measuring the conductivity of the liquid can help to confirm that it is an inorganic acid.
    4. Titration: Titration involves adding a known volume of a standard solution to a sample of the liquid and measuring the volume of the standard solution required to neutralize the acid. This can help to determine the concentration of the acid in the liquid, which can be used to confirm its identity.
