The reactant that has been present in excess in the reaction has been NaCl. Thus, option B is correct.
The balanced chemical equation has been:
From the balanced equation, for complete utilization of 1 mole of sodium chloride, 1 mole of silver nitrate has been used.
The moles of can be given as:
Where, mass of Silver nitrate,
Molecular mass of silver nitrate,
Substituting the values, moles of silver nitrate has been:
Mass of sodium chloride,
Molecular mass of sodium chloride,
Substituting the values, moles of sodium chloride has been:
From the balanced chemical equation,
Since, the available moles of NaCl has been 0.06 mol, and used NaCl has been 0.05 mol. Thus, NaCl has been the excess reactant. Hence, option B is correct.
