The balanced chemical equation for the reaction is:2HNO₃ + Ca(OH)₂ → Ca(NO₃)₂ + 2H₂OFrom the balanced equation, we can see that 2 moles of HNO₃ react with 1 mole of Ca(OH)₂. Therefore, the number of moles of HNO₃ in 50.0 mL of a 0.200 M solution is:n(HNO₃) = 0.200 M * 0.0500 L = 0.0100 molThe number of moles of Ca(OH)₂ in 25.0 mL of a 0.200 M solution is:n(Ca(OH)₂) = 0.200 M * 0.0250 L = 0.00500 molSince the number of moles of HNO₃ is twice the number of moles of Ca(OH)₂, the two solutions will exactly neutralize each other.
