The amount of BaSO ₄ precipitated on mixing BaCl ₂(0.5 M ) with H ₂ SO ₄(1 M ) will correspond to

Step-by-step solution

[ Ba ²⁺ ]=0.5 ~mol ~L ⁻¹ aligned & [ SO ₄²⁻ ]=1 ~mol ~L ⁻¹ & Ba _ (a q) ²⁺+ SO _ 4(a q) ²⁻ BaSO _ 4(s) aligned 0.5 ~mol of Ba ²⁺ would react with 0.5 ~mol of SO ₄²⁻ ions to form 0.5 ~mol of BaSO ₄ .
