The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.

How does the presence of sulfuric acid affect the electrical conductivity of a solution?
Sulfuric acid increases the electrical conductivity of a solution by providing ions that can carry electric current.
What is the difference in conductivity of concentrated and diluted acetic acid?
Concentrated acetic acid has a higher conductivity compared to diluted acetic acid. This is because the concentration of ions in the solution is higher in concentrated acetic acid, leading to better electrical conductivity. Diluting the acetic acid reduces the number of ions present, resulting in lower conductivity.
Are all acid solutions strong electrolytes?
Not all acid solutions are strong electrolytes. Strong acids, such as hydrochloric acid, sulfuric acid, and nitric acid, completely dissociate into ions in solution, leading to strong electrical conductivity. Weak acids, such as acetic acid, only partially dissociate, resulting in a lower concentration of ions and weaker electrical conductivity.
What ions are responsible for the electrical conductivity in hydrochloric acid?
In hydrochloric acid (HCl), the main ions responsible for electrical conductivity are the hydrogen ion (H+) and the chloride ion (Cl-). When HCl is dissolved in water, it dissociates into these ions, which are free to carry electric charge and contribute to the conductivity of the solution.
How do you tell if an acid is a strong acid or weak acid?
Different acids will have varying levels of strength - the most obvious way to see this is to look at the pH of the acid. That is the lower the pH, the stronger the acid. The reason behind this is due to the degree of ionisation of the acid in aqueous solution. For example, hydrochloric acid is a strong acid (complete ionisation) whilst acetic acid is weak as it does not ionise completely.

How are acids related to electrolytes and electrical conductivity?
Acids in aqueous solution are almost always electrolytes that produce hydrogen cations in the solution. Hydrogen cations have the highest specific conductance of any ions in aqueous solution, so that acidic solutions are very strongly conductive if concentrated.
What ions are responsible for the electrical conductivity in hydrochloric acid?
In hydrochloric acid (HCl), the main ions responsible for electrical conductivity are the hydrogen ion (H+) and the chloride ion (Cl-). When HCl is dissolved in water, it dissociates into these ions, which are free to carry electric charge and contribute to the conductivity of the solution.

Why does conductivity decrease with increasing concentration for all acids?
As acid concentration increases, more acid molecules are present to donate protons (H+ ions). Since protons are positively charged, they can increase electrical conductivity by carrying charge. However, at very high concentrations, the acid molecules become so crowded that they can hinder the movement of protons, leading to a decrease in conductivity.
How would the bulb light if you tested copper sulfate and vinegar acetic acid for conductivity?
If the bulb lights up when copper sulfate and vinegar acetic acid are tested for conductivity, it indicates that both solutions are conductive. This means that they contain ions that can carry electrical current. Conductivity in these solutions is likely due to the presence of dissolved ions from the copper sulfate and acetic acid.
Why does 0.02M acetic acid solution have lower electrical conductivity than 0.02 M HCl?
Acetic acid is a weak electrolyte, meaning it partially ionizes in solution, resulting in fewer ions available to conduct electricity compared to HCl, which is a strong electrolyte and fully ionizes in solution, producing more ions for better electrical conductivity.
Is an acid or base better at conducting an electrical current?
Bases are better at conducting an electrical current because they contain ions that can move freely and carry a charge. Acids, on the other hand, may contain fewer ions and therefore have lower electrical conductivity.
How is the strength of an acid measured?
for weak acids e.g lemon juice you would use PH strips dip it in the acid then the strip will change to a certain colour, you then hold this up against a colour chart for the best match. However if your talking about stronger acids I believe you pass an electrical current through it a low PH which equates to it being acidic would give a positive conductivity a high PH which equates to it being alkaline would give a negative conductivity.
What happens to conductivity of water when an acid is dissolved in a base?
When and acid dissolves, ions are released, and the more ions in the water, the more conductivity it has.
