The balanced chemical equation for the reaction between NaOH and HCl is:NaOH + HCl NaCl + H2OFrom the balanced equation, we can see that 1 mole of NaOH reacts with 1 mole of HCl to produce 1 mole of NaCl. Therefore, the mole ratio between NaOH and NaCl is 1:1.Given that 2.5 moles of NaOH reacts with excess HCl, we can use the mole ratio to determine the moles of NaCl produced:2.5 moles NaOH 1 mole NaCl / 1 mole NaOH = 2.5 moles NaClSo, 2.5 moles of NaCl can be produced.
