1) u know that many compounds like alcohol,glucose,urea contains hydrogen atoms in their sturcture. but only acids in their acqueous solution form conducts electricity. prove this with an activity and draw a neat labelled diagram of appartus requried to prove it and explain . why??

2) prctice and draw a neat labelled diagram of liberation co2 on heating of no2 on decomposing Pb(no3)2, liberation of hydrogen by displacement reaction of Zn and Hcl and reduction of copper oxide to Cu??



because acid solutions have ions and the moment of these ions in solutionshelps for flow of electric current through the solution.The positive ion present in HCL solutionis H+.This suggests that acid produce hydrogen ions in solution,what r responsible for their acidic properties.
