Organic Acid Solubility: Step 3 of 3
Extraction of an acid with a base using a separatory funnel is demonstrated. In this step, aqueous acid is added and the result noted.
acids/bases
Copper penny with concentrated nitric acid
The reaction of a copper penny (minted pre-1982) and concentrated nitric acid (15 M) is shown. Red-brown nitrogen dioxide is generated and some of the copper dissolves to form a blue solution of copper(II) nitrate.
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.
