i think they do..but i somehow need to prove that through an experiment.I am not sure which one..so do you have any ideas.....
first i have to carry out an experiment and then i have ot change the pH..how should i do that.

thanks

Absolutely, pH affects the degree of ionization. The more ions present, the greater ability of electron flow. Pure water will not conduct electricity but it auto ionizes enough to provide some current. The more pure the water the more resistance (ohms) it presents to current. So with two probes of an ohmmeter, different aqueous solutions of various pH could be measured to prove this. The pH can be altered easily with household chemicals, vinegar(acetic acid) to decrease pH, or Drano(sodium hydroxide) to increase it. The degree of conductivity will increase in either direction.

Medals are good conductors. something that is a good way to show that the pH level of something effects the conductor is to find something that has an acidic pH level. Stick the medal conductor in the acidic pH solution. now find something that will let out DC current. you cant use AC. Now put two wires letting out DC current in the acidic pH solution and metal and what will happen is the acidic solution will start to dissolve the metal. It speeds up the dissolving process. it should take about a week or two to see a result.

the pH value characterizes the acidity of an element or solution. to change the pH of a solution you need to add some acid or a base. and then do measurements
