When HCl gas is passed through a saturated solution of common salt, pure NaCl is precipitated because
The function of a salt bridge is
BaSO_4 is ionic and PCl_3 is covalent but a saturated solution of BaSO_4 is a weak electrolyte, while that the PCl_3 is a strong electrolyte. Explain.
Wheatstone bridge can be used
Assertion (A) : A saturated solution is that solution which can dissolve any more of solute only on heating. Reason (R) : If a saturated solution is cooled some of the solute can be seen at the bottom of the container.
The electrolysis of an aqueous solution of KNO_3 between platinum electrode gives
What happens, when a hot saturated solution (called super saturated solution) of copper sulphate is allowed to cool in an evaporating dish.
