    Question

    Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids. Describe an activity to prove it.

    Hard Open in App Solution Verified by Toppr Activity:

    Nails are fitted in a cork and are kept in a 100 ml beaker. Then these are connected to the two terminals of a 6 volt battery along with a bulb and a switch. Now some dilute HCl is poured in the beaker and current is allowed to pass through the circuit. The same experiment is carried out using glucose and alcohol solutions separately in place of HCl.

    Observations:

    The bulb glows in HCl solution only. The reason is that HCl solution dissociates into H

    + and Cl –

    ions which help to conduct electricity while glucose and alcohol solutions do not dissociate into ions and so, do not conduct electricity. That is why we find the bulb glowing in HCl solution only.

    Conclusions:

    The above activity proves that acids contain hydrogen but not all compounds containing hydrogen are acids. Due to this reason, compounds such as alcohols and glucose despite containing hydrogen, are not categorized as acids.

    Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids. Describe an Activity to prove it

    Answer:

    Acids are substances that produce hydrogen ions as they dissociate with water. As some compounds dissociate in aqueous solution, hydrogen ions are produced, giving them an acidic character. The release of the H+ ion in water determines whether a compound is acidic or non-acidic.

    HCl → H+ + Cl– HNO3 → H+ + NO3–

    While compounds like glucose and alcohol contain hydrogen, they do not have an acidic nature. The hydrogen in them does not separate as easily as the hydrogen in acids. When they dissolve in water, they will not separate into hydrogen ions.

    Activity to prove alcohols and glucose also contain hydrogen but are not categorized as acids

    Take samples of alcohol, glucose and hydrochloric acid. Take a 100 mL Beaker and take a fork and fix the nails. Place the cork inside the beaker and connect the nails to two terminals of a 6-volt battery through a bulb and a switch. Add some hydrochloric acid to the beaker and on the current. Repeat the procedure with alcohol and glucose.

    In the case of acid, the bulb will glow

    In the case of alcohol and glucose, it does not glow

    Since ions carry the electric current through the solution, the above conclusion can be made. Acid ionizes to give H+ ions in an aqueous medium but glucose and alcohol do not furnish H+ ions even though they contain hydrogen atoms.

    Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids. Describe an Activity to prove it.

    Answer:

    Acids are identified with their capability to ionise and dissociate completely to produce H + ions.Substances like HCl, H 2 SO 4 etc ionise completely to give H + ions and are thus called acids.

    On the other hand, substances like alcohol and glucose do contain Hydrogen but  do not ionise to produce H + ions in an aqueous medium. Hence, they are not categorised as acids.

    We know that acids conduct electricity in aqueous medium but substances like alcohol and glucose don't.

    Activity

    Activity to prove Hydrochloric Acid/Sulphuric Acid conduct electricity but glucose and alcohol do not conduct electricity and thus are not acids.

    (i) Take solutions of HCl , H 2 SO 4 , Alcohol and Glucose in beakers. All these are hydrogen containing compounds.

    (ii) Fix two iron nails on a rubber cork and place the cork in a beaker. Connect the nails to the two terminals of a 6 Volt battery through a switch and a bulb. Pour some HCl into the beaker and switch on the current. You will see that the bulb starts glowing.

    (iii) Repeat the same with H 2 SO 4 and again you will notice the bulb glowing.

    (iv) On repeating the same experiment with Glucose or alcohol solution in the beaker we see that the bulb does not glow.

    Conclusion : Thus it is proved that H 2 SO 4 and HCl conduct electricity because of the presence of H + ions and are thus categorised as acids. Whereas on the other hand glucose and alcohol do not dissociate into H + ions and thus are not categorized as acids.
