Answer 1

$\huge \sf {\orange {\underline {\pink{\underline{Answer :-}}}}}$

Though compounds like alcohol and glucose contain hydrogen but they do not ionise in the solution to produce H+ ions on passing current through them.

• (i) Take solutions of alcohols and glucose.
• (ii) Fix two nails on a cork, and place the cork in 100 mL beaker.
• (iii) Connect the nails to the two terminals of a 6 volt battery through a bulb and a switch,
• (iv) Now pour alcohol in the beaker and switch on the current.
• (v) The bulb does not glow.
• (vi) Repeat the experiment with glucose. The bulb does not glow in this case also.
• (vii) This means no ions or H+ ions are present in the solution.

→This shows that alcohols and glucose are not acids.

Answer:

ANSWER

ANSWERThe 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.

Due to this reason compounds such as alcohols and glucose although contain hydrogen, but they are not categorized as acids.
