Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aque

Question

Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aqueous sodium chloride and liquid water. Supposed 23.3 g of hydrochloric acid is mixed with 10.0 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by this reaction. Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aqueous sodium chloride and liquid water. Supposed 23.3 g of hydrochloric acid is mixed with 10.0 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by this reaction.

Explanation / Answer

the reaction for it is

HCl + NaOH ----------> NaCl + H2O

mass 23.3 g 10.0 g

moles 23.3g / 36.5 g/mol 10.0g / 40.0 g/mol

= 0.638 mol = 0.25 mol

therefore NaOH is the limiting reagent.

and

moles of H2O produced = 0.25 mol

and

maxium mass of H2O produced= 0.25 mol x 18.0 g/mol

= 4.5 grams
