Give a reason for the following:
Ionisation potential increases across a period, from left to right.
From left to right in the periodic table, atomic size decreases smaller the size more the effective nuclear charge. Therefore more energy is required to remove an electron from an atom, therefore, ionization potential increases.
Name the gas that is produced in the following cases:
Action of cold and dilute nitric acid on copper.
Name the gas that is produced in the following cases:
The action of dilute hydrochloride acid on sodium sulphide.
Give a reason for the following:
The conductivity of dilute hydrochloric acid is greater than that of acetic acid.
Name the gas that is produced in the following cases:
Sulphur is oxidized by concentrated nitric acid.
Name the gas that is produced in the following cases:
At the anode during the electrolysis of acidified water.
