As shown in figure insert two nails on the wooden or rubber cork and place it in a beaker. Now connect these iron nails with a bulb, a 6 volt battery and a switch using a wire. Now pour some alcohol or glucose such that the nails will dip into it. Now turn the switch on, you will see that the bulb will not glow. Now empty the beaker and add some HCl aqueous solution at this time the bulb will glow. This proves that an acid can conduct electricity while alcohols and glucose cannot, even when they are containing hydrogen.

Prepare solutions of glucose,alcohol,hydro caloric acid and sulphuric acid

connect two different coloured wires to graphite rods separately in a 100 ml beaker

Connect free ends of the wire to 230volts AC plug and complete the circuit by connecting a bulb to one of the wires now pour some dil. hcl in the beaker and switch on the current

you will notice that the bulb glows only in acid solutions but not in glucose and alcohol solutions glowing of bulb indicates that there is flow of current through the solution acid solutions have ions and the movement of these ions help for flow of electric current through the solution the positive ion present In HCL this suggests that acids produce hydrogen ions in solution which are responsible for there acidic properties. in glucose and alcohol solution bulb did not glow indicating absence of hydrogen ions in these solutions. the acidity of acids is attributed to the hydrogen ions produced by them in solutions.

Answer 2

Answer:

Hydrogen is found in all acids. All acids release hydrogen gas when they react with metals. In water, all acids produce hydrogen ions. Not all hydrogen containing compounds are acidic because not all of them produce hydrogen ions when dissolved in water.

Explanation:

All acids contain hydrogen:

• Acids are described as a substance or element that releases hydrogen (H+) ions into a solution, according to the Arrhenius theory. As a result, there are no Arrhenius acids that do not contain a hydrogen atom.
• A base, according to the Bronsted–Lowry acid–base theory, is any chemical that can take a proton while an acid is any substance that can contribute a proton. As a result, according to this idea, no acids exist that do not contain a hydrogen atom.

All hydrogen containing compounds are not acidic:

• An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen ion, H+).
• Despite the fact that molecules like glucose and alcohol contain hydrogen, they are not acidic. They have a harder time separating their hydrogen than acids do. They will not split into hydrogen ions when dissolved in water. Thus, not all hydrogen containing compounds are not acidic.
