Question

20 gof silver nitrate is mixed with 6 gram of sodium chloride to give silver chloride as precitate find out limiting reagent

Answer 1

Answer:

NaCl

Explanation:

Balanced chemical reaction is .

AgNO3 + NaCl gives AgCl + NaNO3

Molecular mass of AgNO3 is 170

Molecular mass of NaCl is 58.5

number of moles of AgNO3 available is 20/170 = 0.118

number of moles of NaCl available is 6/58.5 = 0.103

One mole of AgNO3 needs one mole of NaCl generally speaking.

here, we have 0.118moles of AgNO3 which will need 0.118 moles of NaCl but only 0.103 is available.

so the reactant which is less in quantity than the required amount is the limiting reagent. NaCl is the limiting reagent.
