Question

What is concentration of nitrate ion if equal volume of 0.1m agno3 and 0.1m nacl are mixed together with solution?

Answer 1

0.1M AgNO3 contains 0.1 moles of Ag+ and 0.1 moles of NO3- ions in 1L of solution. It was mixed with 0.1M NaCl of equal volume.

Here the quantity of NO3- is same but the volume is doubled. So its concentration will be reduced to half. So the concentration of NO3-is 0.05M

Answer 2

Answer:

0.05M

Explanation:

The reaction between AgNo3 and Back is:

AgNo3+Nacl->Agcl(s)+Na++No3-

1 mol 1mol 1mol

01mol 0.1mol 0.1mol

let equal volumes of AgNo3 and Back be 1L, then the total volume will be 2L

Hence (No3-)=0.1mol/2

=0.05M
