Question

100ml of 0.2 M NaCl is mixed with 50ml of 0.5 M AgNo3 solution. Mole of silver chloride formed in the reaction is
1) 0.2
2)0.02
3)0.25
4)0.025

Answer 1

Answer:

option2 ..................

Answer 2

THE MOLES OF OF SILVER CHLORIDE (AgCl) formed is 0.02

When 100 ml 0.2 M NaCl is mixed with 50 ml 0.5 M AgnO3  following reaction take place

• AgNo3 + NaCl -----------> NaNo3 + AgCl

• here we can see that 1  mole of Agno3 reacts with 1 mole of NaCl to form 1 mole of NaNo3 and 1 mole of AgCl

• Moles of NaCl= $M_{1}V_{1}$=0.2 × 100/1000= 0.02 mole

• Moles of AgNo3= $M_{2} V_{2}$ = 0.5 × 50/1000 = 0.025 mole

• here we can see that mole of nacl is less than mole of agno3.

• Hence NaCl is LIMITING

• MOLES OF AgCl formed= 0.02
