Q.
What maximum amount of $ BaS{{O}_{4}} $ get precipitated if 0.5 mole of $ BaC{{l}_{2}} $ is mixed with 1 mole of $ {{H}_{2}}S{{O}_{4}} $ ?

Solution:
Since 0.5 moles of $ BaC{{l}_{2}} $ react with 0.5 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 mole.
