Question

Choose the incorrect option based on the data provided in the table.

Salt	Reactant	Method of Preparation	Nature of salt
$K_{2}S{O}_4$	$K_{2}S+H_2{\mathrm{SO}}_4$	--------	Soluble
${\mathrm{FeCl}}_3$	---------	Direct Combination	-------
------	${\mathrm{BaCl}}_2+H_2{\mathrm{SO}}_4$	Double Decomposition	Insoluble

• A. ${\mathrm{FeCl}}_3$ is insoluble salt.
• B. $K_{2}S{O}_4$is prepared by decomposition method.
• C. Salt formed by method of double
  decomposition is ${\mathrm{BaSO}}_4$
• D. Preparation of ${\mathrm{FeCl}}_3$ uses Fe and Cl
  as reactants.

Answer 1

The correct option is A ${\mathrm{FeCl}}_3$ is insoluble salt.
