50 grams of sodium hydroxide will react with 50 grams of hydrochloric acid to give 50 grams of sodium chloride and 50 grams of water.

Question

Quizplus · Accepted Answer

In the given chemical equation, the molar mass of sodium hydroxide (NaOH) is 40 g/mol while the molar mass of hydrochloric acid (HCl) is 36.5 g/mol. Hence, 50 grams of NaOH would contain 1.25 moles while 50 grams of HCl would contain 1.37 moles. As per the equation, 1 mole of NaOH reacts with 1 mole of HCl to produce 1 mole of NaCl and 1 mole of water. Therefore, 1.25 moles of NaOH would require 1.25 moles of HCl for complete reaction. In this case, since the amount of HCl is more than required, only 1.25 moles of HCl will react, producing 69.6 grams of sodium chloride and 30.4 grams of water. Thus, the given statement is false.
