    What maximum amount of \[BaS{{O}_{4}}\] get precipitated if \[0.5mole\]of \[BaC{{l}_{2}}\] is mixed with \[1\text{ }mole\]of \[{{H}_{2}}S{{O}_{4}}\]?

    A)  \[0.5\text{ }mol\]          

    B)  \[1.0\text{ }mol\]

    C)  \[1.5\text{ }mol\]          

    D)  \[2.0\text{ }mol\]

    Correct Answer: A

    Solution :

                    Since \[0.5moles\]of \[BaC{{l}_{2}}\]react with \[0.5\text{ }mole\] of\[{{H}_{2}}S{{O}_{4}}\]. \[BaC{{l}_{2}}+{{H}_{2}}S{{O}_{4}}\xrightarrow{{}}BaS{{O}_{4}}+2HCl\] Thus, maximum amount of \[BaS{{O}_{4}}\] precipitated is\[0.5\text{ }mole\].
