## Electrical conductivity of hydrochloric acid

The electrical conductivity apparatus circuit is completed by an aqueous solution of hydrochloric acid.

## Electrolysis of a sulfuric acid solution

An electric current is passed through a sulfuric acid solution. Gases collected at the electrodes are tested.

## Electrolysis of a neutral solution animation

This animation simulates the electrolysis of a neutral aqueous solution.

## Electrolysis of hydrochloric acid solution

Electrolysis of a hydrochloric acid solution produces oxygen at the anode and hydrogen at the cathode.

## Electrolysis of hydrochloric acid solution with indicator

In aqueous hydrochloric acid, the electrolyzed solution is acidic at both electrodes.

## Electrolysis of sodium hydroxide solution

Electrolysis of a sodium hydroxide solution produces oxygen at the anode and hydrogen at the cathode.

## Electrolysis of sodium hydroxide solution with indicator

In aqueous sodium hydroxide, the electrolyzed solution is basic at both electrodes.

## Electrolysis of sodium chloride solution

Electrolysis of a sodium chloride solution produces oxygen at the anode and hydrogen at the cathode.

## Electrolysis of sodium chloride solution with indicator

In neutral sodium chloride, base is produced at the cathode and acid at the anode.

## Titration of acetic acid

A simple titration with acetic acid and sodium hydroxide is performed.
