Question

What is the concentration of nitrate ions if equal volumes of 0.1 m agno3?

Answer 1

Answer:

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
