mention the apparatus used In the laboratory to
1 determine the volumetric composition of water
Answers
Answer:
The electrolysis of water, identifying the gases produced, and proving Faraday's laws all involve Hofmann's Voltameter.
Explanation:
August Wilhelm von Hofmann (1818–1892) created a water electrolysis device in 1866 called a "Hofmann voltameter."
It is made up of three upright, linked cylinders, generally made of glass.
A little quantity of sulfuric acid or other ionic chemicals can be added to the inner cylinder's open top to boost conductivity.
The positive and negative terminals of an electrical source are linked to a platinum electrode that is positioned at the bottom of each of the two side cylinders.
Gaseous oxygen and gaseous hydrogen develop at the anode (positive) and cathode, respectively, when current is applied to the Hofmann voltmeter (negative).
Hence, the apparatus used in the laboratory to determine the volumetric composition of water is known as the Hofmann voltameter.

Answer:
Hofmann voltameter
Explanation:
August Wilhelm von Hofmann (1818-1892) developed a water electrolysis device called a Hofmann voltmeter in 1866. It is made up of three upright, linked cylinders, usually made of glass. The top of the inner cylinder is open, allowing water to be added that has been diluted with a substance like sulfuric acid to increase conductivity and complete the circuit. The positive and negative terminals of an electrical source are connected to a platinum electrode that is positioned inside the bottom of each of the two side cylinders. Gaseous oxygen forms at the anode and gaseous hydrogen forms at the cathode when electricity is applied to Hofmann's voltmeter. Water is replaced by each gas, which then gathers at the top of the two outer tubes.
