Question

State the experiment for the identification of NH4+ ion. ​

Answer 1

Answer:

Stefan-Boltzmann law, statement that the total radiant heat power emitted from a surface is proportional to the fourth power of its absolute temperature. Formulated in 1879 by Austrian physicist Josef Stefan as a result of his experimental studies, the same law was derived in 1884 by Austrian physicist Ludwig Boltzmann from thermodynamic considerations: if E is the radiant heat energy emitted from a unit area in one second (that is, the power from a unit area) and T is the absolute temperature (in kelvins), then E = σT4, the Greek letter sigma (σ) representing the constant of proportionality, called the Stefan-Boltzmann constant. This constant has the value 5.670374419 × 10−8 watt per metre2 per K4. The law applies only to blackbodies, theoretical surfaces that absorb all incident heat radiation.

Answer 2

$\huge\underline\pink{\sf Answer}$

Experiment for the identification of NH4+ ion :

✴Ammonia ions are identified by adding

"SODIUM HYDROXIDE " Solution and by

gently heating it..

Identification of presence of NH4+ ions::

✴If the Ammonium ions are present it is converted into Ammonia gas.

✴Ammonia has characteristic choking smell ..

✴This reaction which occurred serves as confirmatory test for NH4+ Ions..

The Effect on Litmus paper if NH4+ ions are present :

✴ It converts moistened red litmus paper to blue color..

✴This also says the presence of NH4+ ions...
